PHY1040-01

A Maxim Integrated Products Brand

125Mbps – 1.25Gbps VCSEL/Laser Driver and Postamplifier

Features

• Common anode VCSEL driver output stage

with 32mA max modulation drive and 20mA

bias current.

Description

The PHY1040-01 is

continuous mode

VCSEL/Laser driver and limiting amplifier for use

within fiber optic modules for SFP and SFF

applications. Used with the PHY1092-01 or

PHY1095-01 transimpedance amplifiers and a low

cost serial EEPROM or microcontroller it forms a

complete SFP module solution.

• Continuous mode LASER driver with up to

80mA modulation and 90mA bias current

• Closed or open loop bias mode with

temperature lookup table

The transmit section integrates a modulator output

stage optimised as a LASER or VCSEL driver in

common anode configurations.

• Temperature compensated modulation current

• Limiting amplifier with programmable low pass

filter and output swing

The bias current can be controlled either by a fast

settling APC loop or in open loop mode which

uses a temperature lookup table.

• Device settings stored in external 2k EEPROM

The receiver includes a limiting amplifier with

programmable bandwidth. A Signal Detect/Loss Of

Signal function is implemented using the input

signal modulation amplitude with user selectable

threshold and hysteresis.

Applications

• Fast Ethernet

• Gigabit Ethernet

• OC-3

Operating with a 3.3V supply and rated from -40 to

+95°C ambient, the PHY1040-01 is housed in a

32pin, 5x5mm, RoHS compliant, QFN package.
