DS1863 19-4883 Rev 2 8/09 Burst-Mode PON Controller With Integrated Monitoring General Description Features The DS1863 controls and monitors all the burst-mode Meets BPON, GPON, and GEPON Timing transmitter and video receiver biasing functions for a Requirements for Burst-Mode Transceivers passive optical network (PON) transceiver. It has an Bias Current Control Provided by APC Loop with APC loop with tracking-error compensation that pro- vides the reference for the laser drivers bias current Tracking Error Compensation and a temperature-indexed lookup table (LUT) that Modulation Current Is Controlled by a controls the modulation current. It continually monitors Temperature-Indexed Lookup Table for high output current, high bias current, and low and high transmit power with its internal fast comparators to Supports 0dB, -3dB, -6dB Power Leveling ensure that laser shutdown for eye safety requirements Settings with No Additional Calibration are met without adding external components. Five ADC Internal Direct-to-Digital Temperature Sensor channels monitor V , internal temperature, and three CC external monitor inputs (MON1, MON2, MON3) that can Five Analog Monitor Channels: Temperature, V , CC be used to meet transmitter and receive monitoring MON1, MON2, and MON3 requirements.
