SY87725LHY

Drivers, Receivers, Transceivers Overview

The SY87725LHY is a single-chip transceiver designed for data rates up to 2.5Gbps, manufactured by Microchip Technology in a 64-pin EPAD-TQFP package. It operates on a single 3.3V supply with typical power consumption of 1W and functions within an ambient temperature range of -40°C to +85°C. The device integrates a clock recovery circuit with a synthesizer generating internal clocks from TTL or PECL REFCLK inputs (77.76MHz or 155.52MHz). It features a 4-bit serial-to-parallel converter on the receive side and a parallel-to-serial converter on the transmit side, utilizing LVDS interfaces for parallel data and CML for serial I/O.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a complete clock recovery and data retiming circuit with an internal synthesizer for stable clock generation during data absence.
• Features industry-standard high-speed differential CML serial I/O and LVDS parallel I/O with internal termination.
• Includes selectable double data rate options and loopback functions for diagnostic verification.
