DESCRIPTION
The DS1852 transceiver monitor manages all system monitoring functions in a fiber optic data
transceiver module, in accordance with proposal SFF-8472. Its functions include 2-wire communications
with the host system, EEPROM memory for identification, tracking, and calibration, an ADC with four
muxing inputs, three fast comparators, and a temperature sensor to monitor an optical transceiver. The
DS1852 has programmable alarm and warning flags for all four analog-to-digital (A/D) conversion
values (three user analog inputs plus supply voltage) as well as the temperature. These conditions can be
used to determine critical parameters inside each module. The three fast comparators have temperature-
compensated programmability. The temperature dependencies of the trip points aid in assessing critical
conditions.
The DS1852 is offered for sale free of any royalty or licensing fees. However, users should be aware that implementation of the SFF-8472
proposed specifications may require the use of an invention covered by patent rights. Since these patents relate to the SFF-8472 specification
and not to the DS1852 itself, licensing questions should be directed to Finisar Corp.
