PRODUCT DESCRIPTION
The ADN2811 provides the receiver functions of quantization,
signal level detect, and clock and data recovery at OC-48 and
OC-48 FEC rates. 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.
The device is intended for WDM system applications and can
be used with either an external reference clock or an on-chip
oscillator with external crystal. Both the 2.48 Gb/s and
2.66 Gb/s digital wrapper rates are supported by the ADN2811,
without any change of reference clock.
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 signal detect circuit indicates when the
input signal level has fallen below a user-adjustable threshold.
The signal detect circuit has hysteresis to prevent chatter at the
output.
The ADN2811 is available in a compact, 7 mm × 7 mm, 48-lead
chip scale package.
