AD9866 is a broadband modem mixed-signal front end with 12-bit D/A converter, 2×/4× interpolation filter, 200 MSPS DAC update rate, integrated 23 dBm line driver and 19.5 dB gain control, 12-bit, 80 MSPS A/D converter, -12 dB to +48 dB low noise RxPGA (< 2.5 nV/rtHz), third order programmable low-pass filter, flexible digital data path interface, half- and full-duplex operation, backward compatible with AD9975 and AD9876, various power-down/reduction modes, internal clock multiplier (PLL), 2 auxiliary programmable clock outputs, available in 64-lead chip scale package or bare die.
The AD9866 mixed‑signal front‑end (MxFE) integrates a 12‑bit DAC, a 12‑bit ADC, programmable gain amplifiers, interpolation filters and a PLL‑based clock multiplier. It supports half‑ and full‑duplex operation for broadband modem applications such as VDSL and power‑line networking.
The device is supplied in a 64‑lead lead‑frame chip‑scale package (LFCSP) and operates from a 3.3 V supply range (‑40 °C to +85 °C). Detailed specifications cover DAC/ADC performance, power consumption, digital interface timing and pin functions.
