AD9860/AD9862 are versatile integrated mixed-signal front-end processors optimized for broadband communication markets. They are cost effective solutions for wireless or wireline standards based or proprietary broadband modem systems, with critical attributes such as dynamic performance, power dissipation, cost, and size.
The AD9860 and AD9862 are versatile mixed‑signal front‑end (MxFE) processors optimized for broadband wireless and wireline communication systems. They integrate dual ADC and DAC paths, programmable gain amplifiers, digital filters, and timing circuitry in a compact 128‑lead LQFP package.
This manual details the device features, functional block diagram, electrical specifications, pin‑out tables, timing characteristics, power‑supply requirements, and ordering information, along with definitions of key performance metrics.
