ADN2811ACP-CML

The ADN2811ACP-CML is a clock and data recovery (CDR) IC from Analog Devices designed for SONET OC-48 and SDH STM-16 applications, including FEC rates. It integrates quantization, signal level detection, and clock recovery functions.

Key electrical specifications include a supply voltage range of 3V to 3.6V (3.3V typical), typical power dissipation of 540 mW, and a maximum data rate of 2.66 Gbps. The device features CML inputs and outputs, a 1:2 input-to-output ratio, and an integrated PLL. It offers a quantizer sensitivity of 4 mV typical and an adjustable slice level range of ±100 mV. The minimum bandwidth is 1.9 GHz, and the loss of signal detect threshold ranges from 3 mV to 15 mV. Supported reference clock frequencies include 19.44 MHz, 38.88 MHz, 77.76 MHz, and 155.52 MHz.

The device is housed in a 48-lead LFCSP package measuring 7mm x 7mm, with surface mount mounting. It operates over a temperature range of -40°C to +85°C. The packaging method is bag. The device is RoHS3 compliant (unverified) and has an MSL of 1 (Unlimited).

The ADN2811ACP-CML is suitable for use in WDM transponders, regenerators, repeaters, test equipment, and backplane applications. It meets all SONET jitter requirements including jitter transfer, generation, and tolerance.
