CY2308ZI-1HT

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2308ZI-1HT is a zero-delay buffer manufactured by Infineon Technologies (formerly Cypress Semiconductor). It operates on a single 3.3V supply and features five LVCMOS outputs. The device supports input frequencies ranging from 10 MHz to 220 MHz, with corresponding output frequencies in the same range. It exhibits low jitter characteristics, specifically 75 ps typical cycle-to-cycle jitter at 66 MHz with a 15 pF load. The component is housed in a 16-pin TSSOP package and functions within an operating temperature range of -40 °C to +85 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero input-output propagation delay adjustable via capacitive load on the FBK input
• Five low-skew LVCMOS outputs organized into two banks of four, three-stateable by select inputs
• Operates at 3.3V with an input/output frequency range of 10 MHz to 220 MHz
• Typical cycle-to-cycle jitter of 75 ps at 66 MHz with 15 pF load

Clock Generators, PLLs, Frequency Synthesizers Applications

• Clock distribution in high-speed digital systems
• Buffering clock signals for memory interfaces
• System synchronization where zero delay is required

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

The CY2308ZI-1HT is listed as an End-of-Life (EOL) product by Infineon Technologies. Availability is restricted or unavailable through standard distributors. Verification of current stock status and EOL notifications is required before procurement planning. Alternative components should be evaluated due to the discontinued status.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a zero-delay buffer with five outputs is required for 3.3V logic systems. Ensure the design accommodates the 16-pin TSSOP package constraints. Verify that the input frequency falls within the 10 MHz to 220 MHz range. Consider the 75 ps jitter specification against system timing requirements. Check for compatible pin-outs if replacing older CY2308 variants.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the CY2308 family of zero-delay buffers. The 'Z' suffix typically denotes the 3.3V operation variant, while 'I' indicates the industrial temperature range (-40°C to +85°C). The 'HT' suffix specifies the tape-and-reel packaging format. The device was originally developed by Cypress Semiconductor before its acquisition by Infineon Technologies.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers must evaluate alternative zero-delay buffers from current Infineon or third-party portfolios. Pin-compatible replacements should be verified against electrical specifications and package dimensions.
