Description
The 1417K5A transceiver is a high-speed, cost-effec-
tive optical transceiver intended for 2.488 Gbits/s
shelf-to-shelf optical interconnect applications as well
as SONET SR OC-48 and SDH I-16. The transceiver
features proven Agere Systems optics and is pack-
aged in a narrow-width plastic housing with an LC
duplex receptacle. The receptacle fits into an RJ-45
form factor outline. The 20-pin package pinout con-
forms to a multisource transceiver agreement.
The transmitter features the ability to interface to both
LVPECL and CML differential logic level data inputs.
The transmitter also features a TTL logic level disable
input and laser bias and back-facet monitor outputs.
The receiver features differential CML logic level data
and clock outputs, a TTL logic level signal-detect out-
put and direct access to the PIN photodetector bias
input for photocurrent monitoring purposes.
