12-/14-Bit Mixed Signal Front-End (MxFE) Processor for Broadband Communications

The AD9860 / AD9862 are versatile integrated mixed signal front ends that are optimized for broadband wireless applications. The AD9860 / AD9862 are cost effective high performance mixed signal solutions for standards based or proprietary fixed access, modem, or wireless networking applications where dynamic performance, power dissipation, cost, and size are critical attributes.

The AD9860 / AD9862 receive path includes dual high-performance, 10-/12-bit, 64 MSPS analog to digital converters, with input buffers, programmable gain amplifiers, and decimation filters. The transmit path contains dual high-performance 12-/14-bit 128 MSPS digital-to-analog converters, programmable gain amplifiers, interpolation filters, a digital Hilbert filter, and digital mixers for complex or real signal up-conversion.
