High-Performance 3V LVTTL/LVCMOS to Differential PECL Clock Translator | Microchip SY89872UMG-TR

In modern high-speed digital systems, the translation of clock signals between different logic families is a critical function for ensuring signal integrity and system synchronization. The Microchip SY89872UMG-TR stands out as a high-performance device designed specifically for converting single-ended 3V LVTTL or LVCMOS clock inputs into low-skew, differential PECL outputs. This capability is essential in applications such as telecommunications infrastructure, networking equipment, and high-end computing, where precise timing and noise immunity are paramount.

Operating from a single 3.3V power supply, the SY89872UMG offers exceptional performance with a maximum operating frequency exceeding 1.5 GHz. Its architecture ensures minimal additive phase jitter, which is crucial for maintaining the overall timing budget of a system. The device features a differential PECL output that provides excellent common-mode noise rejection, making it ideal for driving signals across backplanes or through noisy environments. The input is designed to accept standard 3V LVTTL/LVCMOS levels, offering great flexibility for interfacing with common oscillators, FPGAs, or processors.

A key advantage of this translator is its internal biasing network, which eliminates the need for external bias resistors on the PECL outputs, simplifying board design and reducing component count. The enable/disable function (EN) allows for power management, putting the outputs into a high-impedance state when not in use. The SY89872UMG is offered in a compact 2mm x 2mm 8-UFDFN package, making it suitable for space-constrained applications. Its -40°C to +85°C industrial temperature range ensures reliability across various operating environments.

ICGOODFIND: The Microchip SY89872UMG-TR is an optimal solution for designers seeking a robust, high-frequency clock translator that simplifies the interface between single-ended and differential logic domains while maximizing signal integrity and minimizing design complexity.
