Cypress Semiconductor Corp CY2309ZC-1H

Description
The CY2305/CY2309 is a low-cost 3.3V zero delay buffer designed to distribute high-speed clocks. It accepts one reference input and drives out multiple low-skew clocks. The CY2305 has five outputs, while the CY2309 has nine outputs, grouped as 4 4 1.
The CY2305/CY2309 has 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. The CY2309 has two banks of four outputs each, which can be controlled by the Select inputs.
The CY2305/CY2309 PLLs enter a power down mode when there are no rising edges on the REF input. In this state, the outputs are three-stated and the PLL is turned off, resulting in less than 25.0 μA current draw.
