tion. Performance data (range, power requirements, etc.) may depend on the oper-
ating environment, the area of application, the configuration, and method of control,
as well as on other conditions of use; these may deviate from the technical specifi-
cations, the Design Guide specifications, or other product documentation. The ac-
tual performance characteristics can be determined only by measurements subse-
quent to integration. Variations in the performance data of mass-produced devices
may occur due to individual differences between such devices. Device samples

1.2.2 Cable Replacement Multipoint
Since several devices may be connected with a master device via Bluetooth, several
end devices can also be multiplexed via Bluetooth. This adaptation is shown below
for a desktop device.

In order to handle multiple links a multiplexing protocol is required for the communi-
cation between devices, the BlueRS+ and the host. The BlueRS+ has to be adapted
to the routing scheme of the protocol to transmit the data in an appropriate way. This
includes Bluetooth connection control (i.e. are the Bluetooth links permanently active
or only on demand) and data distribution (i.e. are all data from the host to be for-
warded to all devices or only depending on the address header; are data from the
devices are transmitted to the host transparently or is an address header to be
added). In case you have a multipoint application please contact Stollmann for spe-
cific support.

3 Application Interface
3.1 Power Supply
The BlueMod+B20 requires a power supply with the following characteristics:
3.3V ± 0.1V low noise (≤10mV) >80mA peak
Due to the technological requirements and the pulsed radio transmission the supply
needs to be fed by an ultra fast (response time ≤20µs) linear regulator placed as
close as possible to the VSUP pin (22). Functionality has been verified with the fol-
lowing types: TOREX: XC6204x332xx or XC6401xx42xx
It is also recommended to place a low ESR capacitor with at least 10µF as close as
possible to the VSUP pin (22).
NOTE: You must ensure that during operation the supply voltage never drops below
3.0 V. Otherwise the flash contents (firmware and/or configuration data) can get lost.

3.2 Reset
The BlueMod+B20 is equipped with circuitry for generating Power Down Reset from
the internal core voltage. A reset is generated when the core voltage falls below
typically 1.5V and is released when it rises above typically 1.6V.
Via Pin 31 an external reset is generated by holding RESET# at ≤ 0.3V for ≥ 5ms.
It is strongly recommended to use external Power ON Reset circuitry, which holds
RESET# at ≤ 0.3V for ≥ 5ms after VSUP has stabilized in the recommended volt-
age range.
The following table shows the pin states of BlueMod+B20 on reset.

3.7 PCM Interface
PCM or Pulse Code Modulation is a sampling technique for digitising analogue sig-
nals.
The PCM interface for voice applications is provided via the PCM_OUT, PCM_IN,
PCM_CLK and PCM_SYNC pins.
The PCM interface can act as master or as slave device.
In master mode, clock frequencies of 128kHz, 256kHz or 512kHz can be generated,
when using the internal 4MHz clock. In slave mode, clock frequencies up to
2048kHz are accepted.
The Frame Clock is 8kHz. Long and Short Frame Sync are supported.
BlueMod+B20 interfaces directly to PCM audio devices including the following:
• Qualcom MSM3000 series and MSM5000 series CDMA base band devices
• OKI MSM7705 four channel A-law and µ-law codec
• Motorola MC145481 8-bit A-law and µ-law codec
• Motorola MC145483 13-bit linear codec
• STW 5093 5094 14-bit linear codec
3.8 USB Interface
3.8.1 D+, D-
The BlueMod+B20 contains a full speed USB version 1.1 compliant interface capa-
ble of directly driving a USB cable. The BlueMod+B20 operates as a USB peripheral
and responds to requests from a USB master host controller.
3.8.2 USB Pull-Up Resistor
In self powered mode a 1.5KΩ pull up resistor needs to be connected between PIO2
and the USB D+ line. This pulls the USB D+ line high when the BlueMod+B20 is
ready for enumeration, signalling to the host controller that the BlueMod+B20 is a
full speed (12Mbps) USB device.
In bus powered mode an internal pull up resistor can be used. For details see SW
description.

3.8.3 USB Self-Powered Mode
In USB self-powered mode, the BlueMod+B20 is powered from its own power sup-
ply and not from the USB Vbus line. In order to detect when the USB Vbus line is
powered up, the USB Vbus line is monitored by PIO4 through a voltage divider .

3.8.4 USB Bus-Powered Mode
In USB bus-powered mode, the BlueMod+B20 is powered from the USB Vbus line
by means of a Low Drop Out (LDO) Voltage Regulator. When choosing the LDO
Voltage Regulator for supplying the +3.3V power to the BlueMod+B20, some factors
that need to be considered are:
• The voltage specification for the USB Vbus line is +4.75V to +5.25V.
• The total current required (average and peak) for the design.
• The voltage regulator’s drop out voltage vs. output current.
• The voltage regulator’s power dissipation over the operating temperature range.
• Filtering requirements on the USB Vbus line to attenuate noise above the volt-
age regulator’s bandwidth.
• The suspend state current draw.
