ADN2819 is a high performance multirate clock and data recovery IC with integrated limiting amp, supporting up to 2.7Gb/s bandwidth.
The ADN2819 is a multirate clock and data recovery IC designed for SONET/SDH, Gigabit Ethernet, and 15/14 FEC rates. It meets jitter transfer, generation, and tolerance requirements and operates from a single 3.3 V supply with low power consumption.
The device is offered in a 7 mm × 7 mm 48‑lead LFCSP package and supports selectable reference clock frequencies of 19.44 MHz, 38.88 MHz, 77.76 MHz, or 155.52 MHz. It includes features such as loss‑of‑signal detection, loopback test mode, output squelch, and programmable slice level adjustment.
