PRELIMINARY
Section 5-5
Compact Front End Board (C-FEB)
5-5-1 General Information
The main purpose of the Venue Go™ Front End Board (C-FEB) is to transmit/receive all the channels
data signals to/from the 128 TRX channels on the board. In addition, it contains all the control and status
lines required for HV mux setup, probe selection, reading probes status, probes information and the
power supplies for transmission and operation of the scanner.
The Venue Go™ Front End Board is designed to support the cSound SW beam-forming architecture
for 128 channels.
5-5-2 C-FEB Interfaces
The External Interfaces from the Front End are:
• The Main DC IN power connector that connects the AC/DC Adaptor 24 V supply to the scanner.
• Optional Power Docking connector for future Power Supply from a Cart that contains the following:
• DC IN Supply line from 24 V AC/DC Adaptor or External Battery
• Cart Present Signal
• Scanner Present Signal sent to the Cart
• Scanner Disconnect early warning Signal
• Interface to External Batteries Module that contain:
• SMBUS Interface
• External Battery Present Signal
• 3 x RS Probe Connectors located on the C-PSB
The C-FEB is connected to the C-BEB via 2 connectors:
• High Speed Data and Control Connector that consist of the following:
• PCI-e channel (1 Lane Gen2) for Setup and communication between the BEP and the DSP
located on the C-FEB via PCI Bridge
• PCI-e channel (8 lanes Gen2) for Acquired Data Transfer between FE and BE
• SMBUS Channel between the BMC and the PMC to transfer BE status information or
communication messages from the scanner application.
• Control and Status Signals between the BE BMC and the PMC
• Power Connector that consist of the following Supply voltages:
• 12v Main Supply voltage to the C-BEB and to the Display connected to it.
The C-FEB is connected to the C-PSB via 2 connectors and consist of the following Interfaces:
• 28 Transmit and Receive System channels
• Dedicated I2C channel for PSB Setup and Status Reading
• Discrete Control Signals
• I2C channel for Probe ID Reading and PSB Debug Information.
• LVDS channels for Matrix Probe Setup and Status Reading (Reserved, but not used in C-PSB)
• PSB DC Supply
