The DS1852 from Dallas Semiconductor is claimed to be the industry's first optical transceiver diagnostic monitor to implement the enhanced features defined by the SFF-8472 MSA, and is aimed in reducing the component count and size, and speed up the design of optical transceivers.

The device features manages all system monitoring functions required for SFF-8472-compliant optical transceivers, and features EEPROM memory for identification, tracking, and calibration. It also has an ADC with four multiplexed inputs for with programmable alarm and warning flags for monitoring system parameters.

Housed in a 5-by-5mm BGA package, the DS1852 also integrates three comparators, a two-wire serial interface, and a temperature sensor to enable the device to alert the system to out-of-tolerance conditions for a variety of measured parameters.

The DS1852 operates from a 2.7V to 5.5V source over a -40C to 100C temperature range, and is priced at $3.31 each for quantities of 1,000-up.
