Intel Corporation Signal Switches, Multiplexers, Decoders FAGD1655348BA

The FAGD1655348BA is a high-performance 2.5 Gbit/s 4:1 multiplexer designed for fiber optic communication systems, compliant with ITU-T STM-16 and SONET OC-48 standards. It multiplexes four 622.08 Mbit/s data streams into a single 2.488 Gbit/s output, utilizing an external master clock at either 38.8 MHz or 77.6 MHz. The device features an on-chip phase-locked loop (PLL) for precise retiming of high-speed data, along with a high-current laser driver capable of sinking up to 60 mA. The multiplexer can be bypassed to allow direct input of a 2.5 Gbit/s signal to the laser driver. It operates on a single -5 V supply and is housed in a 48-pin JEDEC standard Thin Quad Flat Pack (TQFP-48L-EDQUAD) package. The device also includes features such as mark/space ratio monitoring and adjustment, making it suitable for various telecommunications and data communication applications. Power dissipation is typically 0.95 W.
