Description
The 1430G5-Type transceiver is a high-speed, cost-
effective optical transceiver that is compliant with the
International Telecommunication Union Telecommu-
nication (ITU-T) G.957 specifications for use in
SONET and SDH long-reach applications. The
1430G5 operates at the OC-3/STM-1 rate of
155 Mbits/s. The transceiver features Agere Sys-
tems’ optics and is packaged in a narrow-width plas-
tic housing with two 1 meter fiber pigtails terminated
with LC connectors. The 20-pin package and pinout
conform to a multisource transceiver agreement.
The transmitter features differential LVPECL logic
level data inputs, a LVTTL logic level disable input.
The receiver features differential LVPECL logic level
data and clock outputs, and a LVTTL logic level
signal-detect output.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
