AD9866BCPZ

The AD9866BCPZ from Analog Devices is a cost-effective, 3.3V CMOS mixed-signal front end (MxFE) IC tailored for broadband modem applications. This device integrates both transmit (Tx) and receive (Rx) path functionalities, supporting data rates up to 80 MSPS. Key electrical specifications include a 12-bit DAC with a 200 MSPS update rate and a 12-bit ADC operating at 80 MSPS. It also features an integrated line driver with gain control and a low-noise RxPGA with a noise spectral density below 2.5 nV/√Hz.

The AD9866BCPZ boasts a flexible digital data path interface and supports half- and full-duplex operation, making it suitable for various transceiver designs. Power-saving modes are available for reducing consumption in unused blocks. The IC is housed in a 64-lead chip scale package (64-LFCSP-VQ), facilitating integration into compact designs.

This MxFE is backward-compatible with previous Analog Devices parts like the AD9975 and AD9876. Its architecture includes an internal clock multiplier (PLL) for generating required clocks from a single source. The device is well-suited for applications such as Powerline networking, VDSL, and HPNA.
