CY2308ZC-1H

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2308ZC-1H is a 3.3V Zero Delay Buffer manufactured by Infineon Technologies (formerly Cypress Semiconductor). It features an on-chip PLL that locks to an input clock presented on the REF pin, with feedback obtained from one of the outputs. The device provides eight LVCMOS outputs organized into two banks of four, which can be three-stated via select inputs. It operates within a frequency range of 10 MHz to 133 MHz and supports a supply voltage of 3.0 V to 3.6 V. The component is housed in a 16-pin TSSOP package and is rated for commercial operating temperatures between 0 °C and 70 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero input-output propagation delay adjustable by capacitive load on the FBK input
• Two banks of four low skew outputs controllable by two select inputs
• On-chip PLL enters power down state when no rising edges are present on the REF input

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Ensure compatibility with system voltage requirements and load capacitance specifications before procurement. Confirm current availability status as product lifecycles may change.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for applications requiring zero delay buffering at frequencies up to 133 MHz. Verify that the required output configuration matches the available banking options. Ensure the PCB layout accommodates the specified load capacitance limits for the target operating frequency to maintain signal integrity.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY2308 family of 3.3V Zero Delay Buffers. The 'Z' suffix indicates a 16-pin TSSOP package, while 'C' denotes the commercial temperature range. The '-1H' designation specifies the high-drive version of the base -1 configuration, providing faster rise and fall times compared to standard variants.
