DESCRIPTION
The SA900 is a monolithic high performance, multi-function transmit
modulator for use in cellular radio applications, fabricated in QUBiC
BiCMOS technology. The SA900 features both analog (AMPS)
mode and complex, I/Q digital (NADC IS–136) mode quadrature
modulation functions, a PLL synthesizer with VCO, crystal oscillator,
programmable prescalers and Gilbert cell multiplier phase detector
with programmable charge pump output. The DUALTX output can
be used in DUAL mode cellular phone applications with the AMPS
and NADC modulation being applied to the I/Q baseband inputs.
The DUALTX output also provides 6-bit power control with 40dB of
gain control in 0.63dB steps. In addition, buffered crystal oscillator
programmable prescaler outputs are provided to support system
clock reference needs. Programming of the SA900 functions are
realized by a high speed 3-wire serial interface. The SA900 can be
programmed into a sleep mode (low current mode providing crystal
oscillator and Master Clock functions), a standby mode (providing
crystal oscillator, Master Clock, System Clock 1 and Transmit LO
buffer functions), and the AMPS mode and the DUAL mode
configurations.
