AD28MSP01KP-REEL

Overview

The AD28MSP01KP-REEL is a complete analog front end designed for high-performance DSP-based modems. It integrates all necessary data conversion, filtering, and clock generation circuitry to implement echo-cancelling modem functionality with a single host digital signal processor. The device supports software-programmable sample rates and clocking modes compatible with established modem standards. It operates on a single +5 V supply and includes features such as linear-coded 16-bit sigma-delta ADC and DAC, on-chip anti-alias and anti-image filters, and a transmit digital phase-locked loop for terminal synchronization.

Feature Summary

• Integrates complete analog I/O port including 16-bit sigma-delta ADC and DAC for DSP-based applications
• Includes on-chip anti-alias and anti-image filters along with digital resampling and interpolation filters
• Supports multiple sampling rates and clocking modes via software programmability
• Features independent transmit and receive phase adjustment with synchronous and asynchronous operation modes

Applications
