Description
The CXA3003R is a baseband analog processing
IC for dual-mode CDMA/FM cellular phone. The
CXA3003R interfaces between the inter-frequency
section and the digital processing circuitry of the
telephone. The receive circuit functions primarily
convert analog IF signals to the analog baseband
frequency range and to convert the analog
baseband signals into digital signals. Transmit
circuits convert digital data into analog baseband
signals which are then up-convert to the IF
frequency range.
Features
Receive signal path includes:
·
IF to baseband down conversion
·
Built-in trim-free low-pass filter for CDMA and
FM
·
Built-in A/D convertor convert the RX base
band signal to the digital signal
·
Analog output Receive Signal Strength
Indicator (RSSI) for CDMA
·
Local Oscillator for I-Q mixer
Transmit signal path includes:
·
Built-in D/A convertor convert the digital I-Q
data to the analog baseband signal
·
Built-in trim-free low-pass filter for CDMA and
FM
·
Baseband to IF up-conversion
·
Local Oscillator for I-Q mixer
·
Built-in PLL for TX IF
Built-in House keeping A/D convertor
Low power consumption in all modes
Single 3.3 V power supply
