Infineon CY2304SXC-1

扇出缓冲器（分配），零延迟缓冲是时钟时钟

Overview

The CY2304SXC-1 is a Zero Delay Buffer designed to distribute high-speed clocks in PC and workstation. The part has an on-chip phase-locked loop (PLL) that locks to an input clock presented on the REF pin. The PLL feedback is required to be driven into the FBK pin and can be obtained from one of the outputs. The input-to-output skew is guaranteed to be less than 250ps and output-to-output skew is guaranteed to be less than 200ps. The CY2304SXC-1 has two banks of two outputs each. The CY2304SXC-1 PLL enters a power-down state when there are no rising edges on the REF input. In this mode, all outputs are three-stated and the PLL is turned off, resulting in less than 25µA of current draw. Multiple CY2304SXC-1 devices can accept the same input clock and distribute it in a system. In this case, the skew between the outputs of two devices is guaranteed to be less than 500ps. The CY2304-1 is the base part, where the output frequencies equal the reference if there is no counter in the feedback path.
