CY23FP12OXC

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY23FP12OXC is a 200 MHz field-programmable zero delay buffer in a 28-pin SSOP package. It features an integrated PLL for low jitter clock distribution, supporting operating frequencies from 10 MHz to 200 MHz. The device provides twelve LVTTL outputs divided into two banks (Bank A and Bank B), each with independent power supply pins configurable for 2.5 V or 3.3 V operation. Key electrical specifications include a typical output-to-output skew of 35 ps and cycle-to-cycle jitter of 110 ps at the same frequency. It operates within a commercial temperature range of 0 °C to 70 °C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Fully field-programmable via flash technology, allowing customization of input/output dividers, feedback topology, and output inversions.
• Twelve low-skew LVTTL outputs grouped into two independently powered banks (A and B) support split 2.5 V or 3.3 V rails.
• Integrated PLL supports reference frequencies from 10 MHz to 200 MHz with programmable M, N, and X dividers.
• Features auto power-down circuitry that reduces current draw to less than 50 µA upon reference clock failure.

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution for ASICs and microprocessors requiring low jitter.
• Systems requiring glitch-free switching between dual reference clocks using REFSEL.
• Multi-voltage domain designs utilizing separate 2.5 V and 3.3 V power supplies for different output banks.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'X' indicates the standard tube packaging configuration. Confirm the 'C' suffix denotes the commercial temperature range (0 °C to 70 °C). Ensure compatibility with the CY3672-USB programmer for initial configuration, as the device requires programming before circuit installation. Check for lead-free compliance status if required by specific manufacturing standards.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when flexible post-divider ratios and multiple output configurations are needed from a single IC. Choose the industrial variant (CY23FP12OXI) if operation below 0 °C or above 70 °C is required. Consider the tape-and-reel option (suffix T) for automated assembly processes. Ensure the application can accommodate the 28-pin SSOP footprint and thermal requirements.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The CY23FP12 belongs to the Cypress 23FP series of field-programmable zero delay buffers. Unlike fixed-function buffers, this family allows users to define specific divider values and output behaviors during the programming phase. The OXC variant specifically refers to the commercial grade version in the 28-pin SSOP package, distinct from the industrial grade (OXI) or reel-packaged versions.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct pin-compatible replacements within the same package and voltage profile should be sought from the CY23FPxx series. Verify that any substitute supports the required 200 MHz maximum frequency and has equivalent programmability features. Cross-model substitution may require reprogramming if the target device lacks identical divider ranges or output bank structures.
