2 Introduction
Venice 8 has been designed as the next step in the evolution of connected audio products. Based
around the new Frontier Silicon Chorus 3 baseband audio processor, it builds on the
functionality of the Venice 6.2 Internet radio module to facilitate a new type of touchscreen
connected audio product, with new features, performance and ergonomics ensuring the highest
possible performance.
Venice 8 features a new, highly customisable UI, making full use of the latest TFT display
technology with resistive touch, to improve ease-of-use.
2.1 Features
Figure 2 shows a block diagram of Venice 8. The main components are the RF front end,
Chorus 3 FS1230 baseband processor, serial boot Flash, SDRAM and audio DAC.
The Chorus 3 processor is based around a high performance advanced RISC/DSP. In addition to
the core DAB demodulation functions, this processor is well suited to running digital radio/
connected audio application code.
Venice 8 measures 65 x 80 mm (see Chapter 9: Mechanical specification). All components are
mounted on the top of the module. The underside of the module has a solid copper ground plane.
With the exception of the connectors and screw holes, all components are fitted inside the four-
chamber screening can. The RF, Wi-Fi, baseband and analogue audio sections are all screened
from each other.
Venice 8 has been designed to use a 3.5 inch TFT colour touchscreen module with a resolution
of QVGA (320 x 240) and an LED backlight.
Stereo audio outputs are provided in analogue line level and S/PDIF digital formats
Venice 8 has two MAC addresses, one for Wi-Fi and one for Ethernet. It is supplied with 4 MAC
address labels for the Wi-Fi (the Ethernet MAC address is the Wi-Fi MAC address plus one).

3 Power supplies
Venice 8 requires a 1.2 V ± 5%, supply for the digital baseband and 3.3 V ± 5% for the RF circuits
and other baseband devices such as the audio DAC and 5 V ± 5% for Wi-Fi and Ethernet . All
supplies should be clean with low ripple. Any noise on these supplies will affect performance.
The module includes some supply filtering on its DC supply lines. This takes the form of a Pi
network with a ferrite bead inductor in the supply line and with one or more capacitors to ground
on either side.
The voltage rails must be regulated with over-specified regulators and bulk decoupling to cope
with the burst requirements of the DAB receiver, Wi-Fi TX and to reduce noise and ripple. The
capacitors and regulators should be mounted as close as possible to J1.
For best performance, the system PCB should include a solid ground plane. If this is not
possible, the PCB should use large power tracks, with the ground connections from each
regulator and smoothing capacitor joining close to the module.
3.1 Power-on timing
The 5.0 V, 3.3 V and 1.2 V supplies may be applied in any order but extended periods of delay
should be avoided.
3.2 Power-off timing
Venice 8 is designed so that the power can be removed in any order at any time without affecting
the module.
3.3 Reset thresholds
The 1.2 V, 3V3 and 5V supplies to Venice 8 should be kept within the operating limits. The
module’s operation may become unstable if the supply deviates from these limits.
Venice 8 incorporates an on-board reset to cope with supply interruptions.
Supply Symbol Parameter Typ Units
3.3V VTH+ Reset threshold rising level 2.25 V
VTH- Reset threshold falling level 2.15
1.2V VTH+ Reset threshold rising level 0.95
VTH- Reset threshold falling level 0.90
Table 2: Reset threshold levels

Venice 8 CONFIDENTIAL NDA 3 Power supplies
3.4 Boot up considerations
1. Care must be taken to ensure that SPDIF_OUT (pin 19) is driven low during the reset cycle.
2. USB_VBUS_FAULT (pin 38) must not have any external pull-ups fitted as there is a 100 kΩ in
the module. Failure to do this will result in boot up problems.
14/41 FSM 0002 8613 Rev 3
Datasheet CONFIDENTIAL NDA Venice 8
4 Software
Frontier Silicon normally provides Venice 8 pre-installed with software. This can be configured
to customer requirements.
The module is intended to be used as the basis for a standalone connected audio system (see
Figure 1 on page 9). The only external parts needed are a power source, antenna(s), TFT touchpad
display, infrared receiver, backlight, iPod authentication, keypad (two switches), rotary encoder
(optional), amplifier and speaker(s).
Soft FM (RDS) software allows the module to function as an FM radio receiver without the need
for a separate FM tuner chip. An FM user interface provides access to all RDS features.
Please contact Frontier Silicon for further information.
