The 2417J4A transceiver is a high-speed, cost-effective 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 agreement. 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 signaldetect output.
