PHY1071-01QD-BR

Overview

The PHY1071-01 is a combined VCSEL driver and limiting amplifier designed for small form-factor modules in Fibre Channel applications. It supports multi-rate operation from 125Mbps to 2.125Gbps. The transmitter integrates a high-speed output stage with programmable bias and modulation currents, controlled via a 2-wire serial interface. Key specifications include a maximum modulation drive of 16mA and a bias current up to 20mA. The receiver features an integrated limiting amplifier with selectable swing CML output. The device operates within a temperature range of -40°C to +85°C and is housed in a 36-pin 6mm x 6mm QFN package.

Procurement Notes

Verify the specific ordering suffix (e.g., RR) against the manufacturer's datasheet to confirm packaging type and RoHS compliance status. Ensure the component matches the required data rate and module form factor for the target application.

Selection Notes

Select based on the required data rate (up to 2.125Gbps) and VCSEL configuration (common cathode or common anode). Consider the need for digital diagnostics support via the 2-wire serial interface and the operating temperature range (-40°C to +85°C).

Part Context

The PHY1071-01 is part of the PHY1071 series by Analog Devices Inc./Maxim Integrated. It is specifically engineered for optical transceivers requiring integrated driver and receiver functionality with digital monitoring capabilities.

Replacement Considerations

Check for direct substitutes like the PHY1071-01QD-RR. Verify pin compatibility and electrical specifications before substitution.
