Microchip Technology, Inc. Clock Buffers, Drivers SY89847UMG

The SY89847UMG is a precision LVDS fanout buffer designed to distribute clock signals with a 1:5 output configuration and features a 2:1 multiplexer. It operates at a supply voltage of 2.5V ¬±5% and is capable of handling input signals with a wide voltage range. The device supports a throughput of DC to over 1.5 GHz, with propagation delays guaranteed to be less than 1000 ps and rise/fall times under 210 ps. A notable feature is its fail-safe input, which prevents output oscillation when the input clock is invalid, ensuring reliable operation. The internal termination architecture allows for direct interfacing with various differential signals, including AC- and DC-coupled inputs, without the need for external termination resistors. The SY89847UMG is suitable for applications requiring ultra-low jitter clock distribution, with specifications indicating random jitter below 1 ps RMS and total jitter under 10 ps peak-to-peak. This component is housed in a compact 32-pin QFN package and is rated for an industrial temperature range of -40¬8C to +85¬8C, making it suitable for a variety of environments, including telecom and datacom applications.
