Reference design files
A complete reference design including PCB layout and PCB design guidelines is available
from LumenRadio to make integration easier. Please send your inquiry to LumenRadio
for details.
PCB mounting
Internal or External Antenna?
For short distances the modules´ internal antenna will perform well. But if the design is
to be placed inside a metal enclosure, or if there is a need to cover large distances, an
external antenna is necessary. An external antenna MUST at least be designed for
operation between 2.4 – 2.48GHz
Always use external antennas with a 50ς characteristic impedance.
Internal Antenna
If the internal antenna is considered, the product case needs to be of a RF transparent
plastic material. The circuit board that will hold TiMo needs to be designed so that the
internal chip antenna radiates efficiently. Avoid any ground planes near the antenna chip.
When placing TiMo on a circuit board:
xPlace the module as close to the host circuit board edge as possible with the
antenna pointing outward.
xNote the absence of ground plane near the chip antenna on the modules´ circuit
board.
xRemove any copper from the main board as specified in section “Layout
ExampleLayout Examples”
xAvoid using metal structures such as mounting hardware close to the antenna
chip.
Layout considerations for the main (Customer) board.
TiMo has been specifically designed in order to achieve good RF performance. In order to
maintain this, there are some guidelines that we would like to stress:
The use of ground planes also on the main board cannot be overemphasized. Good
decoupling of any high speed digital circuitry is a must. Many embedded type
microprocessors today has clock frequencies with clocks or over tones that reaches well
into the GHz range. It is perfectly possible for an embedded design to pass any EMC
certification and still cause disturbances that will block the RF reception of the TiMo
module. The sensitivity of the TiMo receiver is -96dBm therefore it is recommended to
keep disturbances below -100dBm in the frequency range of operation
ᑖṬᔿⲴ
Ͳ9Ͳ
A near field probe connected to a spectrum analyzer will show if there are any
disturbances present on the 2.45 GHz band generated by the microprocessor or any
other device that is placed on the main board. Pay special attention to readymade LAN-
products "Server in a RJ connector". They pass EMC certifications, but some of them
radiates badly on 2.45 GHz. If disturbances can be seen on a spectrum analyzer - then
the TiMo module will have impaired reception.
TiMo has a supply voltage decoupling on the circuit board. The supply voltage still needs
to be adequately filtered. If any disturbance or intermittent communication failures occur,
as one of the trouble shooting steps - check the supply voltage for drop-outs, switch
supply ripple etc.
Layout Example
1. The TOP layer inside the footprint must be free from copper. There is a ground
plane on TiMo, but there are also supply lines. It is an unnecessary risk to rely on
solder mask lacquer for isolation.
2. The area around the antenna must be kept clear from copper on all layers. This is
shown in the picture below. This shows inner layer 1 (next to TOP)

TiMo reflow soldering specification
TiMo is a surface mount device (SMD) designed to be easily manufactured including
reflow soldering to a PCB.It isultimately theresponsibility of the customer to choose the
appropriate solder paste and to ensure oventemperatures during reflow meet the
requirements of the solder paste. TiMo surface mount module conforms to JSTD-020D1
standards for reflow temperatures.
Temperatures should not exceed the minimums or maximums presented in table below:

LED outputs
Status
The status LED (STATUS_LED) indicates the status of the TiMo RX RDM. The LED
indicator pin is an output pin capable of sourcing 5mA at the VDD voltage. An appropriate
current limiting resistor must be connected in series with the LED.
Constant off (0V): Not linked to any transmitter
Flashing: off (0V) 100 ms / on (VDD) 100 ms: linked to a transmitter, but no active radio
link
Flashing: off (0V) 900 ms / on (VDD) 100 ms: Active radio link, no DMX present
Constant on (VDD): Active radio link, DMX data present
Linked
The Linked LED (LINKED) indicates whether the TiMo RX RDM is linked to a transmitter
or if it’s available to be linked. High level (VDD) on this pin indicates a linked state; low
level (0V) indicates that the TiMo RX RDM is not linked.
RF Link
A high level (VDD) on the RF Link LED output (RF_LINK) indicates that the TiMo RX RDM
is within range from the transmitter it is linked to and that an active radio link from the
transmitter is present.
DMX
The DMX LED (DMX_LED) indicates if a valid DMX stream is received from the
transmitter. A high level (VDD) indicates that DMX is present, a low level (0V) indicates
that no valid DMX is present.
RDM LED
A high level (VDD) on the RDM LED output (RDM_LED) indicates that the TiMo RX RDM is
performing RDM activity.
Ͳ13Ͳ
Radio level
TiMo RX RDM has 5 output signals for controlling radio level LEDs in the form of a bar
graph (RDI_LVL0 - RDI_LVL4). Operation of these, and suggestion of LED colors, can be
found in the table below.
Signal name Suggested LED color On when signal quality
RDI_LVL0 Red below ~10%
RDI_LVL1 Amber / Yellow above ~20%
RDI_LVL2 Green above ~40%
RDI_LVL3 Green above ~60%
RDI_LVL4 Green above ~80%
Link switch input
The link switch input can be used to interface with a momentary closing push button to
facilitate a simple user interface when not using the SPI interface to integrate into a host
device’s menu system.
Please refer to the example schematic for details on how to connect the push button.
This signal shall be pulled to VDD using an external 4.7kȍ-10kȍ resistor, when used, to
ensure proper function.
The switch input has two functions: unlink the receiver from a transmitter or to force
driver update mode. Please see the table below for details about the functions of the
switch input.
Function Conditions
Unlink from
transmitter Hold signal low (button pressed) for >3 seconds.

Antenna selection
The antenna selection input can be used to select the required RF antenna for use on
TiMo RX RDM. This pin is internally pulled high. This pin can be overridden by writing the
ANTENNA register.

SPI interface
The SPI interface gives access to all features of the TiMo RX RDM. The interface consist
of five digital signals (VDD max):
xIRQ – Interrupt signal. Active low, configurable through the interrupt mask
register.
xCS – SPI Chip select, active low.
xSCK – SPI clock input
xMOSI – SPI data input
xMISO – SPI data output
Interface description
Bit and byte order
The data on the SPI bus is clocked with most significant bit first. All multi-byte register
data are sent in big-endian byte order.
Clock polarity
Data is valid in the low-to-high transition of SCK. This is also known as the clock being
active high with valid data on the leading clock edge.
Maximum clock speed
The maximum clock speed supported by TiMo RX RDM is 2MHz. Clock speeds above this
limit may result in unexpected behavior.
Setup time
The SPI slave unit has a setup time of 4 Njs after the high-to-low transition of the CS
signal.
SPI operation
SPI transactions
All SPI transactions start with a high-to-low transition on the CS pin. The CS pin must be
held low during the entire SPI transaction.
The IRQ_FLAGS register is always shifted out as the first byte of each transaction.
Figure 3: Example SPI transaction
Ͳ15Ͳ
SPI commands
All SPI command sequences, except for the NOP command, consist of two SPI
transactions. The first transaction shall be one byte long, this is the command byte. The
second transaction is the payload. The second transaction must not be started until the
TiMo RX RDM has confirmed the command by a high-to-low transition on the IRQ pin.
The first byte being sent to TiMo RX RDM in the second transaction will be ignored,
however it is suggested this byte is being sent as 0xFF. See below for an example full
SPI command sequence.
NOTE: Bit 7 in the IRQ flags register MUST be observed. A ‘1’ in this bit means that the
SPI slave module is unable to process the current transaction, and the full command
sequence MUST be restarted – this means sending the command transaction again.
Figure 4: Example SPI command sequence with a pending IRQ when sequence started
The available SPI commands are listed in the table below.
