Description
The MP5494 is a high-accuracy, high-integration analog front-end for photonics control. It integrates 4-channel, 12-bit current sources (IDACs); 12-channel, 12-bit configurable voltage outputs (VDACs); 12-channel multi-function input/outputs (I/Os) for voltage and current monitor input; and a 6-channel voltage analog-to-digital converter (ADC) input.
The IDACs provide a 300mA current source in each channel for laser diode driving, and the VDACs can provide configurable voltage for heaters with up to ±30mA of current capability. The photodetector (MPD) current monitor function can be supported by the multi-function I/Os, which feature selectable current-source and current-sink modes.
The MP5494 integrates a 12-bit ADC that can be selected to monitor the 12-channel multi-function I/O current or voltage, ADC1 through ADC6 voltage, IDAC1 through IDAC4 voltage, or the 4 power sources' voltages.
The MP5494 requires a minimal number of external components and is available in a space-saving WLCSP-56 (3.6mmx3.5mm) package.

APPLICATION
OPTICAL MODULESAPPLICATIONOptical modules are optical transceivers used for high-speed data transmission, and are used anywhere larger amounts of data needs to be sent and received. From data centers to telecom, short or long range, optical modules are ideal for large, efficient data transfers. Optical modules can range in size and bandwidth, with the newest generation supporting up to 400GB/s. Due to the large amounts of ...
