Microchip Technology, Inc. Clock Buffers, Drivers SY89829UHI

The SY89829UHI is a dual 1:10 LVPECL clock driver designed for high-performance applications requiring low voltage operation at 2.5V or 3.3V. It features a multiplexed input that accepts either LVPECL or LVDS signals, making it suitable for redundant clock switchover applications. The device guarantees a maximum toggle frequency of over 2GHz and offers low channel-to-channel skew of less than 50ps, which is critical for maintaining signal integrity in high-speed systems. The SY89829UHI includes internal termination for LVDS inputs, eliminating the need for external components, and has a synchronous output enable (OE) pin to prevent runt clock pulses during transitions. It operates over a temperature range of -40¬8C to +85¬8C and is packaged in a compact 64-pin EPAD-TQFP format, which aids in reducing overall system size and cost. This clock driver is ideal for use in high-performance PCs, workstations, and parallel processor-based systems.
