ASM5I9773A is a low-voltage high-performance 200-MHz PLL-based zero delay buffer designed for high speed clock distribution applications. It features multiple output and input frequency ranges and supports 2.5V or 3.3V operation. The product also has features such as output enable/disable, low output duty cycle variation, and low output-output skew.
The ASM5I9773A zero‑delay buffer operates from a 2.5 V or 3.3 V supply and delivers up to twelve clock outputs across three banks. It features a PLL with bypass mode, spread‑spectrum support, and programmable output dividers that allow a wide range of output‑to‑input ratios.
The datasheet lists the device's electrical characteristics, including input and output voltage ranges, current consumption, and timing parameters, as well as absolute maximum ratings, package information (52‑pin 1.0 mm TQFP), and ordering codes for both tray and tape‑and‑reel formats.
