A Maxim Integrated Products Brand
PHY1040-01
Description
The PHY1040-01 is a 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.
The transmit section integrates a modulator output
stage optimised as a LASER or VCSEL driver in
common anode configurations.
The bias current can be controlled either by a fast
settling APC loop or in open loop mode which
uses a temperature lookup table.
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.
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.
125Mbps – 1.25Gbps VCSEL/Laser Driver and Postamplifier
Features
Common anode VCSEL driver output stage
with 32mA max modulation drive and 20mA
bias current.
Continuous mode LASER driver with up to
80mA modulation and 90mA bias current
Closed or open loop bias mode with
temperature lookup table
Temperature compensated modulation current
Limiting amplifier with programmable low pass
filter and output swing
Device settings stored in external 2k EEPROM
Applications
Fast Ethernet
Gigabit Ethernet
OC-3
