Burst mode laser driver targets next gen PONs

The M02180 low power, highly integrated, programmable burst mode laser driver is integrated with continuous mode limiting amplifier and clock and data recovery designed for passive optical network (PON) optical network unit/optical network terminal (ONU/ONT) applications up to 12.5 Gbps. The M02180 laser driver can be configured in three selectable modes of operation. It offers open loop operation with look-up tables, single closed loop control using monitor photodiode feedback or proprietary dual closed loop operation for low cost BOSA-on-Board applications. 

The laser driver features a limiting amplifier with 6-mV input sensitivity and integrated CDR with reference free operation and can be bypassed to support non-standard data rates. The driver includes an internal state machine controller and non-volatile memory with digital diagnostics, performing all the functions necessary for standalone operation without an external microcontroller. It also boasts a high voltage dc/dc controller for avalanche photodiode biasing with a built-in temperature based look-up table stored in an EEPROM. It is available in a 4.5 x 4.5-mm QFN package and supports industrial temperature operations.
