FEATURES
DUAL RATE 1773 FIBER OPTIC TRANSCEIVER
HC1773
The HC1773 chip is intended to be used in a hybrid package
with a photo diode, a transimpedance amplifier, a crystal
and an LED or laser diode. Interfacing is intended to be via
a protocol chip. Information is transmitted over the fiber
optic cable in either 1Mbps or 20Mbps 1773 format. The
transceiver chip recovers clock and data from the transim-
pedance amplifier's output for 20Mbps data, but only recov-
ers the data in the 1Mbps mode. The transceiver chip does
not decode the Manchester data, but instead treats the
1Mbps Manchester data as 2Mbps NRZ data, and the
20Mbps Manchester data as 40Mbps NRZ data. An LED or
laser diode is also driven with data received from the
protocol chip.
