Burst mode laser driver integrates lifting amp & CDR

It offers open loop operation with look-up tables, single closed loop control using monitor photodiode feedback or MACOM’s proprietary dual closed loop operation for low cost BOSA-on-Board applications. The device features a limiting amplifier with 6mV input sensitivity and integrated CDR with reference free operation and can be bypassed to support non-standard data rates.

The M02180 includes an internal state machine controller and non-volatile memory with digital diagnostics, performing all the functions necessary for standalone operation without an external MCU. The internal state machine provides customers with the ability to acquire and scale industry standard monitoring parameters in real time. The M02180 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.

MACOM’s M02180 provides low power operation, typically less than 90mA, and also offers sleep modes, burst-off current reduction modes and optional 2.5V power supply operation for further power reduction.

“MACOM continues to expand the industry’s most comprehensive optical product portfolio for fibre access networks,” said Angus Lai, Director of High-Performance Analogue Product Marketing, MACOM. “This highly integrated device minimies power consumption and external parts count, provides design flexibility and simplifies manufacturing processes, enabling our customers to develop the best in class 10G PON optical solutions.”

The M02180 is available in a 4.5mm² QFN package and supports industrial temperature operations. Device, evaluation board and reference design are sampling now.
