DS1884 SFP and PON ONU Controller with Digital LDD Interface
The DS1884 controls and monitors all functions for SFF, SFP, and SFP+ modules including all SFF-8472 functionality. The combination of the DS1884 with the MAX3710 supports all transmitter and receiver functionality. The DS1884 includes modulation current control and APC set-point control with tracking error adjustment. It continu-ally monitors RSSI for LOS generation. A 13-bit analog-to-digital converter (ADC) monitors VCC, temperature, laser bias, laser modulation, and receive power to meet all monitoring requirements. Receive power measurement is differential with support for common mode to VCC. A 9-bit digital-to-analog converter (DAC) is included with temperature compensation for APD bias control.
