Microchip Technology, Inc. Clock Buffers, Drivers SY89871UMI-TR

The SY89871UMI-TR is a programmable clock divider and fanout buffer from Quarktwin Technology Ltd., designed to operate at frequencies up to 2.5GHz. It features two matched-delay output banks: Bank A provides an undivided pass-through output, while Bank B offers programmable division ratios of 2, 4, 8, or 16. The device ensures matched delay across all outputs, regardless of the divider setting, with a typical rise and fall time of less than 250ps and a propagation delay of less than 670ps. This clock buffer supports a wide range of input standards, including LVPECL, LVDS, CML, and HSTL, and includes a unique internal termination design for flexible interfacing. It operates on a power supply of either 3.3V or 2.5V and is rated for an industrial temperature range of -40¬8C to +85¬8C. The device is packaged in a compact 16-pin QFN format, making it suitable for space-constrained applications. Applications for the SY89871UMI-TR include SONET/SDH systems, transponders, and oscillators, making it a versatile choice for high-speed clock distribution needs.
