Continuous Rate 12.3 Mb/s To 675 Mb/s Clock And Data Recovery IC With Integrated Limiting Amp
The ADN2814 provides the receiver functions of quantization, signal level detect, and Clock and Data Recovery for continuous data rates from 12.3 Mb/s to 675 Mb/s. The ADN2814 automatically locks to all data rates without the need for an external reference Clock or programming. All SONET jitter requirements are met, including jitter transfer, jitter generation, and jitter tolerance. All specifications are quoted for 40C to +85C ambient temperature, unless otherwise noted.
This device, together with a PIN Diode and a TIA preamplifier, CAN implement a highly integrated, low cost, low power Fiber Optic Receiver
The receiver front end loss of signal (LOS) detector circuit indicates when the input signal level has fallen below a useradjustable threshold. The LOS detect circuit has hysteresis to prevent chatter at the output.
The ADN2814 is available in a compact 5 mm 5 mm 32-lead chip scale package.
Applications SONET OC-1/3/12 and all associated FEC rates ESCON, Fast Ethernet Serial Digital Interface (DTV) WDM transponders Regenerators/repeaters Test equipment Broadband cross-connects and routers
