Overview
The ADN2890ACPZ-RL7 is a high-gain limiting amplifier designed for SONET, Gigabit Ethernet, and Fibre Channel optical receivers. It accepts differential input levels up to 2.0 V p-p with a sensitivity of 3 mV p-p. Operating from a single 3.3 V supply, it delivers CML outputs with 700 mV p-p differential swing and 80 ps rise/fall times. The device integrates a programmable loss-of-signal detector and an SFF-8472 compliant received signal strength indicator. It dissipates 130 mW and is housed in a 16-lead LFCSP package.
Feature Summary
- Integrates quantization and loss of signal detection functions
- Provides on-chip RSSI measurement for average power monitoring
- Features low power dissipation with single-supply operation
- Offers space-saving lead frame chip scale packaging
Applications
- SFP/SFF/GBIC optical transceivers
- OC-3/12/48, GbE, and Fibre Channel receivers
- 10GBASE-LX4 transceivers
- WDM transponders
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct reel configuration. Confirm that the component meets RoHS compliance requirements as indicated by the Z suffix. Check for any updates regarding the CP-16-22 package option before finalizing procurement plans.
Selection Notes
Select this component for applications requiring integrated LOS detection and RSSI functionality to reduce external circuitry. Ensure the design supports single 3.3 V supply operation and accommodates the 130 mW power dissipation. Verify PCB layout capabilities for the 3 mm × 3 mm LFCSP package and thermal management requirements.
Part Context
This part belongs to the ADN2890 series of limiting amplifiers manufactured by Analog Devices. It is specifically optimized for high-speed optical receiver applications where signal quantization and power monitoring are required within a compact form factor.
Replacement Considerations
Consult official documentation for confirmed substitute part numbers. No direct replacements are identified in the provided source material.
FAQ
How is the Loss of Signal (LOS) threshold adjusted?
The LOS threshold is set by connecting a resistor between the THRADJ pin and VEE, allowing for user-adjustable trip points.
What is the function of the RSSI_OUT pin?
The RSSI_OUT pin provides a current output directly proportional to the average PIN photodiode current, enabling accurate on-chip average power measurement.
