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 rate is 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.
