Microchip Technology, Inc. Interface - Drivers, Receivers, Transceivers SY87725LHY-TR

The SY87725LHY-TR is a single-chip transceiver designed for data rates up to 2.5Gbps, suitable for applications in BPON, GPON, GEPON, and EPON systems. It operates with a single 3.3V supply and has a typical power consumption of 1W. The device supports downstream data rates of 2.5G, 1.25G, and 625Mbps, and upstream rates of 1.25G, 625M, and 156Mbps. This transceiver features a 4-bit SerDes architecture with LVDS interfaces, providing a serial data input sensitivity of 30mV. It includes a clock recovery and data retiming circuit, along with a synthesizer for both transmit and receive functions. The internal clock can be generated from an externally supplied TTL or PECL reference clock, ensuring stable operation even in the absence of transitions on the input data stream. The SY87725LHY-TR also offers a loopback function for diagnostics, a training mode for fast lock acquisition, and a TTL-CML translator for MAC-to-laser diode driver burst control. It is packaged in a 64-pin EPAD-TQFP format and is available in a Pb-Free version. This product is suitable for engineers looking for a reliable transceiver for fiber-to-the-home (FTTH) or fiber-to-the-premises (FTTP) applications.
