Description
The MC145483 is a 13-bit linear PCM Codec-Filter used in digital communication systems to perform voice digitization and reconstruction. This component is designed to operate in both synchronous and asynchronous applications, and comes in 20-pin SOG and SSOP packages. It contains an on-chip precision reference voltage and can operate with a single 3V power supply.
Specifications and Features
- 13-bit linear ADC/DAC conversions with 2s complement data format
- Typical power dissipation of 8mW, power-down of 0.01mW
- Fully-differential analog circuit design for lowest noise
- Transmit band-pass and receive low-pass filters on-chip
- Transmit high-pass filter can be bypassed by pin selection
- Active R-C pre-filtering and post-filtering
- On-chip precision reference voltage of 0.886 V for a –5dBm 600Ω
- 3-terminal input op amp can be used, or a 2-channel input multiplexer
- Receive gain control from 0dB to –21dB in 3dB steps in synchronous operation
- Push-pull 300Ω power drivers with external gain adjust
Application Scenarios
The MC145483 can be used in digital communication systems that require voice digitization and reconstruction. It is designed to operate in both synchronous and asynchronous applications.
