www.analog.comPRODUCT DESCRIPTION
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 automati-
cally 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
chip scale package.
