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 PHY1095-01 transimpedance amplifier and a low-cost serial EEPROM or microcontroller, the device forms a complete SFP module solution. The transmit section integrates a modulator output stage optimized 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 the -40°C to +95°C ambient operating temperature range, the PHY1040-01 is housed in a 32-pin, 5mm x 5mm, RoHS-compliant QFN package.
