DS1863
Burst-Mode PON Controller With Integrated Monitoring
Complete Control, Calibration, and Monitoring Solution for GPON, BPON, and GEPON Transceivers
|
Status
Active: In Production.
Description
The DS1863 controls and monitors all the burst-mode transmitter and video receiver biasing functions for a passive optical network (PON) transceiver. It has an APC loop with tracking-error compensation that provides the reference for the laser driver's bias current and a temperature-indexed lookup table (LUT) that controls the modulation current. It continually monitors for high output current, high bias current, and low and high transmit power with its internal fast comparators to ensure that laser shutdown for eye safety requirements are met without adding external components. Five ADC channels monitor VCC, internal temperature, and three external monitor inputs (MON1, MON2, MON3) that can be used to meet transmitter and receive monitoring requirements.
