Optical transceiver diagnostic monitor

27 March 2002 Opto-Electronics

Dallas Semiconductor's DS1852 is the first optical transceiver diagnostic monitor implementing the enhanced monitoring features defined in the SFF-8472 Multisource Agreement (MSA) proposal. The DS1852 manages all system monitoring functions required for SFF-8472-compliant optical transceivers. A high level of integration reduces component count and size. Functions include: EEPROM memory for identification, tracking, and calibration; an ADC with four muxed inputs for monitoring system parameters; a temperature sensor; three fast comparators; and a 2-wire serial interface. Programmable alarm and warning flags for all four ADC inputs and a temperature sensor enable the device to alert the system to out-of-tolerance conditions for a variety of measured parameters. An evaluation kit is available. The DS1852 is offered in space-saving 5 x 5 BGA package (0,8 mm pitch) and operates from 2,7 to 5,5 V over -40 to +100°C.
