Analog Devices AD9865 Mixed‑Signal Front‑End Datasheet
The AD9865 is a mixed‑signal front‑end (MxFE) IC designed for transceiver applications such as power‑line networking, VDSL and HPNA. It provides both transmit (Tx) and receive (Rx) paths with flexible digital interfaces, power‑saving modes, and high isolation for half‑ and full‑duplex operation. The Tx path includes a 10‑bit DAC, programmable interpolation filters and a line driver, while the Rx path features a programmable low‑noise PGA, tunable low‑pass filter and a 10‑bit ADC.
The device operates from a 3.3 V supply, includes an on‑chip PLL clock multiplier, and is available in a 64‑lead chip‑scale package. Detailed specifications cover resolution, update rates, gain ranges, power consumption, and timing for both half‑ and full‑duplex data interfaces.
