PI6C2408集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

描述 Description

The PI6C2408 is a PLL-based, zero-delay buffer, with the ability to distribute eight outputs of up to 140 MHz at 3.3 V. Two banks of four outputs exist, and, depending on product option ordered, can supply either reference frequency, prescaled half frequency, or multiplied 2x or 4x input clock frequencies. The PI6C2408 family has a power-sparing feature: when input SEL2 is 0, the component will 3-state one or both banks of outputs depending on the state of input SEL1. A PLL bypass test mode also exists. This product line is available in high-drive and industrial environment versions.

特性 Features

• Maximum rated frequency: 140 MHz

• Low cycle-to-cycle jitter

• Input to output delay, less than 150ps
