The SY89465UMY-TR is a device commonly used in clock buffering, driving and timing applications, and it is part of a series of industry-leading high performance clock buffers available from IDT. This device provides an adjustable regulated clock output with maximum frequency up to 925 MHz, making them suitable for a wide array of high speed applications, including microcontrollers and digital signal processors. The SY89465UMY-TR’s architecture provides a low cost and reliable solution to bypass long clock traces with minimal impact on signal integrity.

The SY89465UMY-TR features Ultra Low Skew, 3 differential outputs, 4 LVCMOS outputs, high-performance output isolation, adjustable drive strength, and adjustable skew. The three differential outputs are designed to drive multiple signals which can be determined by selecting the required signal combination in the feedback tree accordingly. The device also has a fully adjustable skew between the outputs by setting the CLKFB divider value, with values available from 1x to 10x. In addition, the output current can be adjusted from 1mA to 10mA, allowing for a wide range of applications.

The SY89465UMY-TR works on the principle of clock buffering, where it buffers a clock signal from an input gate and sends it through the output side. It uses an impedance-matched clocking structure that makes each part of the structure contributing equally to the output, reducing the overall voltage noise. The clock signals are also regulated through a feedback system that senses the voltage level of the output clock relative to the input clock and adjusts the current accordingly, ensuring the output clock is accurate with the correct frequency.

In addition to clock buffering, the SY89465UMY-TR is widely used for clock driving and timing applications. The device’s adjustable drive strength and adjustable skew make it perfect for applications that require accurate clock timing and low jitter, such as clock and data recovery systems, clock synchronization, and timing distribution. The device also allows for a wide range of drives, from slow to fast, helping to reduce the overall power consumption.

Overall, the SY89465UMY-TR is an excellent solution for clock buffering, driving and timing applications. Its adjustable drive strength and adjustable skew allows for a wide range of applications, while its low voltage and power consumption make it suitable for handheld and low power applications. Furthermore, the device’s low jitter, high performance output isolation and impedance-matched clocking structure make it ideal for high speed applications, such as clock and data recovery systems, clock synchronization, and timing distribution.
