GENERAL DESCRIPTION
The ADN2892 is a 4.25 Gbps limiting amplifier with integrated
loss of signal (LOS) detection circuitry and a received signal
strength indicator (RSSI). This part is optimized for Fibre
Channel (FC) and Gigabit Ethernet (GbE) optoelectronic
conversion applications. The ADN2892 has a differential input
sensitivity of 3.5 mV p-p and accepts up to a 2.0 V p-p
differential input overload voltage. The ADN2892 has current
mode logic (CML) outputs with controlled rise and fall times.
The ADN2892 has a selectable low-pass filter with a −3 dB
cutoff frequency of 1.5 GHz. By setting BW_SEL to Logic 0, the
filter can limit the relaxation oscillation of a low cost CD laser
used in a legacy 1 Gbps FC transmitter. The limited BW also
reduces the rms noise and in turn improves the receiver optical
sensitivity for a lower data rate application, such as 1× FC and
GbE.
By monitoring the bias current through a photodiode, the on-
chip RSSI detector measures the average power received with
2% typical linearity over the entire valid input range of the
photodiode. The on-chip RSSI detector facilitates SFF-8472-
compliant optical transceivers by eliminating the need for
external RSSI detector circuitry.
Additional features include a programmable loss-of-signal
(LOS) detector and output squelch. The ADN2892 is available
in a 3 mm × 3 mm, 16-lead LFCSP.
