Description
Available in a small form-factor, RJ-45 size, plastic package,
the 2417J4A Transceiver is a high-performance, cost-
effective optical transceiver for Gigabit Ethernet 1000Base-LX
applications.
Features
s Gigabit Ethernet 1000Base-LX compliant
s Small form factor (SFF), RJ-45 size, multisourced
10-pin package
s LC duplex receptacle
s Uncooled 1300 nm laser transmitter with automatic
output power control
s Transmitter disable input
s Wide dynamic range receiver with InGaAs PIN
photodetector
The 2417J4A transceiver is a high-speed, cost-effec-
tive optical transceiver that is compliant with the
IEEE ® 802.3z Gigabit Ethernet Physical Medium
Dependent (PMD) 1000Base-LX specifications using
a long-wavelength laser. The transceiver features the
latest generation of Agere Systems optics and is
packaged in a narrow-width plastic housing with an
LC duplex receptacle. This receptacle fits into an
RJ-45 form-factor outline. The 10-pin package and
pinout conform to a multisource transceiver agree-
ment.
The transmitter features differential LVPECL logic
level data inputs and an LVTTL logic level disable
input. The receiver features differential LVPECL logic
level data outputs and an 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.
