The CY7B9945V-5AXC is a high-speed multi-phase PLL clock buffer designed for optimizing timing in high-performance computer and communication systems. It operates with input and output frequencies ranging from 24 MHz to 200 MHz and features a maximum total timing budget (TTB,Ñ¢) of 500 ps. The device provides ten LVTTL outputs capable of driving 50 Ω terminated lines with low output-output skew of less than 200 ps. This clock buffer allows for phase adjustments in increments of 625 ps to 1300 ps, with a total adjustment range of up to ±10.4 ns. It supports multiply or divide ratios from 1 to 12 and includes a dedicated feedback output for enhanced functionality. The device is fault-tolerant, featuring selectable reference inputs that accommodate both LVTTL and LVPECL signals, ensuring reliable operation even when switching between clock sources. The CY7B9945V-5AXC operates at a supply voltage of 3.3 V and is rated for an industrial temperature range of -40 °C to +85 °C. It is packaged in a 52-pin TQFP format, making it suitable for various applications requiring precise clock distribution and minimal jitter.
