FEATURES
GENERAL DESCRIPTION
Input sensitivity: 4 mV p-p
The ADN2891 is a 3.2 Gbps limiting amplifier with integrated
loss-of-signal (LOS) detection circuitry and a received signal
strength indicator (RSSI). This part is optimized for SONET,
Gigabit Ethernet (GbE), and Fibre Channel optoelectronic
conversion applications. The ADN2891 has a differential input
sensitivity of 4 mV p-p and accepts up to a 2.0 V p-p differential
input overload voltage. The ADN2891 supports current mode
logic (CML) outputs with controlled rise and fall times.
80 ps rise/fall times
CML outputs: 700 mV p-p differential
Programmable LOS detector: 3.5 mV to 35 mV
Rx signal strength indicator (RSSI)
SFF-8472-compliant average power measurement
Single-supply operation: 3.3 V
Low power dissipation: 145 mW
Available in space-saving 3 mm × 3 mm, 16-lead LFCSP
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.
Extended temperature range: 40°C to +95°C
SFP reference design available
APPLICATIONS
SFP/SFF/GBIC optical transceivers
OC-3/OC-12/OC-48, GbE, Fibre Channel (FC) receivers
Additional features include a programmable loss-of-signal
(LOS) detector and output squelch.
10GBASE-LX4 transceivers
WDM transponders
The ADN2891 is available in a 3 mm × 3 mm, 16-lead LFCSP.
