AD9860/AD9862 is a mixed signal front-end processor from Analog Devices. It has high performance, low power consumption, low cost and small size. It is suitable for wireless or wired standard based or proprietary broadband modem systems.
The AD9860 and AD9862 are mixed‑signal front‑end (MxFE) processors optimized for broadband wireless and wireline communication systems. They integrate dual ADCs and dual DACs with programmable gain, filters, and timing circuitry, supporting both real and complex signal paths.
Key features include dual 10‑/12‑bit ADCs (64 MSPS) and dual 12‑/14‑bit DACs (128 MSPS), programmable sigma‑delta output, auxiliary ADC/DAC channels, DLL clock multiplier, and a 128‑lead LQFP package. Detailed specifications, pin‑out diagrams, and timing characteristics are provided for system designers.
| Receive ADC resolution | 10/12 bits |
|---|---|

The devices are rated for an industrial temperature range of –40 °C to +70 °C, and they have been characterized to operate up to +85 °C in half‑duplex mode.
Both parts are supplied in a 128‑lead low‑profile quad flat‑pack (LQFP).
The transmit DACs can update at up to 128 MSPS.
Each DAC can deliver a full‑scale output current of 20 mA.
