High-Performance 3V LVTTL/LVCMOS Clock Fanout Buffer: Microchip SY89321LMG-TR

In the realm of high-speed digital systems, the integrity and precise distribution of clock signals are paramount. The Microchip SY89321LMG-TR stands out as a premier solution, a high-performance 1:4 LVTTL/LVCMOS clock fanout buffer engineered to meet the stringent demands of modern applications. Operating from a single 3.3V ±10% power supply, this device is specifically designed to distribute high-frequency, low-jitter clock signals across multiple destinations with exceptional fidelity.

A key strength of the SY89321LMG-TR lies in its ultra-low additive phase jitter performance, which is critical for maintaining signal integrity and minimizing timing errors in sensitive systems such as telecommunications infrastructure, networking hardware, and high-end test and measurement equipment. It features four synchronous outputs, ensuring minimal skew between them. The device supports a wide range of input signals, accepting LVTTL, LVCMOS, LVPECL, and CML logic levels, providing significant design flexibility. Its differential input includes a built-in termination resistor, simplifying board layout and improving signal quality by reducing reflections.

Housed in a compact, space-efficient 2x2 mm 8-MLF® package, the SY89321LMG-TR is an ideal choice for space-constrained designs. It also incorporates an output enable (/OE) pin, allowing for control over the outputs to enter a high-impedance state, which is crucial for power management and system testing. With its robust performance, low power consumption, and excellent reliability, this fanout buffer ensures that clock timing budgets are met with a significant margin.

ICGOOODFIND: The Microchip SY89321LMG-TR is a superior choice for designers seeking a reliable, high-performance clock distribution solution. Its combination of low jitter, wide input compatibility, and a small form factor makes it exceptionally well-suited for advancing the performance of next-generation digital systems.
