CY2308SI-1HT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2308SI-1HT is a zero-delay buffer manufactured by Cypress Semiconductor Corp, now part of Infineon Technologies. It operates at 3.3 V with an input frequency range of 10 MHz to 133 MHz. The device features low skew outputs and adjustable zero input-output propagation delay via capacitive load on the FBK input. It supports multiple configurations and includes two banks of four three-stateable outputs controlled by select inputs. Typical cycle-to-cycle jitter is 75 ps at 66 MHz with a 15 pF load.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the CY2308 series of zero-delay buffers from Cypress Semiconductor. The 'SI' suffix typically denotes industrial temperature range (-40°C to +85°C) and specific package options, while '1HT' indicates tape and reel packaging. The device was originally designed by Cypress before its acquisition by Infineon Technologies.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same family include CY2308ZXI-1HT or CY2308ESXC-2, provided voltage levels and output configurations match the design requirements. Verify that the substitute supports the required 3.3 V operation and 133 MHz maximum frequency.
