Hot-selling and scarce ADN2818ACPZ Clock and Data Recovery ICs LFCSP32 spot stock

Product Descriptions

The ADN2817/ADN2818 provide the receiver functions ofquantization, signal level detect, and clock and data recovery forcontinuous data rates from 10 Mbps to 2.7 Gbps.The ADN2817/ADN2818 automatically lock to all data rates without the need foran external reference clock or programming.All SONET jitterrequirements are exceeded,including jitter transfer,jitter generation,and jitter tolerance. All specifications are quoted for −40°C to+85°C ambient temperature, unless otherwise noted .

This device, together with a PIN diode and a TIA preamplifier,can implement a highly integrated, low cost, and low powerfiber optic receiver.

The ADN2817/ADN2818 have many optional features availablethrough an I²C interface . For example, the user can read backthe data rate onto which the ADN2817 or ADN2818 is locked,or the user can set the device to lock only to one particular datarate if provisioning of data rates is required.A BERMON circuitprovides an estimate of the received bit error rate (BER) withoutinterruption of the data . Alternatively, the user can adjust thedata sampling phase to optimize the received BER 

The ADN2817/ADN2818 are available in a compact 5 mm ×5 mm, 32-lead, lead frame chip scale package .
