PCF50732 Applications
- Low power and low voltage device in 0.25 micron CMOS technology; supply voltage: analog 2.7 V (typical) and digital 1.5 V (typical)
- patible with GSM phase 2 and DCS1800 remendations
- plete in-phase and quadrature ponent interface paths between the Digital Signal Processor (DSP) and RF circuitry
- plete linear PCM CODEC for audio signal conversion between earphone/microphone and DSP
- Four auxiliary analog inputs for measurement purposes (e.g. battery monitoring)
- Three auxiliary analog outputs for control purposes (i.e. AFC, AGC and power ramping control)
