ADN2812

Continuous Rate 12.3 Mb/s to 2.7 Gb/s Clock and Data Recovery IC with Integrated Limiting Amp
Manufactured by:

Product Details

The ADN2812 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 12.3 Mb/s to 2.7 Gb/s. The ADN2812 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 −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, 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 user-adjustable threshold. The LOS detect circuit has hysteresis to prevent chatter at the output.

The ADN2812 is available in a compact 5 mm × 5 mm 32-lead lead frame chip scale package (LFCSP).

Applications

  • SONET OC-1/OC-3/OC-12/OC-48 and all associated FEC rates
  • Fibre Channel, 2× Fibre Channel, GbE, HDTV
  • WDM transponders
  • Regenerators/repeaters
  • Test equipment
  • Broadband cross-connects and routers

Overall performance of the device is good. With reference clock, the acquisition time is quite small (important, as our incoming signal is not continuously available). External limiting amplifier seems to yield better results, though.
