Infineon CY2305SXC-1T

扇出缓冲器（分配），零延迟缓冲是时钟时钟

Overview

The CY2309 is a low-cost 3.3V zero delay buffer designed to distribute high-speed clocks and is available in a 16-pin SOIC or TSSOP package. The CY2305SXC1 is an 8-pin version of the CY2309. It accepts one reference input, and drives out five low-skew clocks. The -1H versions of each device operate at up to 100-/133-MHz frequencies, and have higher drive than the -1 devices. All parts have on-chip PLLs which lock to an input clock on the REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad.

• 10-MHz to 100-/133-MHz operating range, compatible with CPU and PCI bus frequencies• Zero input-output propagation delay• 60 ps typical cycle-to-cycle jitter (high drive)• Multiple low-skew outputs — 85 ps typical output-to-output skew — One input drives five outputs (CY2305) — One input drives nine outputs, grouped as 4 + 4 + 1 (CY2309)• Compatible with Pentium-based systems• Test Mode to bypass phase-locked loop (PLL) (CY2309 only [see “Select Input Decoding” on page 2])• Available in space-saving 16-pin 150-mil SOIC or 4.4-mm TSSOP packages (CY2309), and 8-pin, 150-mil SOIC package (CY2305)• 3.3V operation• Industrial temperature available
