The AD9860/AD9862 are versatile integrated mixed-signal front-ends (MxFE) that are optimized for broadband communication markets. The AD9860/AD9862 are cost effective, mixed signal solutions for wireless or wireline standards based or proprietary broadband modem systems where dynamic performance, power dissipation, cost, and size are all critical attributes.
The AD9860 and AD9862 are mixed‑signal front‑end (MxFE) processors optimized for broadband communication applications. They integrate dual‑channel ADCs and DACs, programmable gain amplifiers, digital Hilbert and interpolation filters, and a serial SPI interface.
The document provides detailed functional block diagrams, electrical specifications, timing characteristics, pin configurations, absolute maximum ratings and ordering information for the 128‑lead LQFP package.
| ADC resolution | 10‑bit (AD9860) / 12‑bit (AD9862) |
|---|---|
