4.2.1.4.
FPGA
FPGA (IC103) has the following features.
(1) ST-BUS I/F, BBIC PCM I/F
Extracts voice data from ST-BUS digital data and changes format to BBIC PCM format, then provides it to BBIC(IC100).
(2) Superframe detection, delay compensation
Detects super frame synchronisation signal from HK bit in the ST-BUS digital data and compensates time difference of delay
caused by the different cable length from CSIF card, then provides it to PSYNC pin of BBIC(IC100).
caused by the different cable length from CSIF card, then provides it to PSYNC pin of BBIC(IC100).
(3) Address decoder, internal registers
Address decoder to generate chip select signal for other ICs and internal registers to set FPGA operation.
4.2.1.5.
RF Interface Circuit
Data signals for RF control and RX/TX data is connected between BBIC and RF block.
The modulated signal is provided to 2 antennas via CN901 and CN900.
