Coder is used to perform block encoding, decoding, and ciphering
according to GSM algorithms A5 and A5/2.
The ASIC takes care of the interface between the DSP and the RFI: TX
modulator, RX filter, TX and RX sample buffers and controlling state
machine. The interface to RFI is done using 12 bit data bus, 4 bit address
bus, RDX and WRX. There is also data acknowledge (DAX) signal from
RFI to ASIC. Also in this block is the serial RF synthesizer interface
(SCLK, SDAT, SENA1) and the digital RF control signals (RXPWR,
TXPWR, TXP, SYNTHPWR)
Main components
– D2CA ASIC, physically in MCM2
– 2 x TC7S00F (D300,D301) NAND gate
Inverter buffer stage is used for converting the low–level VCXO
clock to valid logic levels.
– Transistors BC848W (V330) and BCW30 (V331)
The SIM power switch.
RFI
Introduction
The RFI block consists of the RFI ASIC and its reference voltage
generator. This block is an interface between the RF and baseband
sections. The RFI block has the following functions:
– IF receiving and A/D conversion
– I/Q separation
– I– and Q–transmit and D/A conversion
– AFC D/A conversion
– TXC D/A conversion (burst template)
– analog AGC and digital LNA gain switch
