CY23FP12OXC-002T

Clock Buffers, Drivers Overview

The CY23FP12OXC-002T is a field-programmable zero delay buffer manufactured by Cypress Semiconductor Corp. It operates on a single 3.3 V supply and supports frequencies from 10 MHz to 200 MHz. The device features twelve low-skew outputs divided into two banks, each with independent power pins for split 2.5 V or 3.3 V operation. It includes an integrated PLL optimized for low jitter and noise rejection. Key electrical parameters include a typical output-to-output skew of 35 ps and cycle-to-cycle jitter of 110 ps at the same frequency.

Clock Buffers, Drivers Feature Summary

• Fully field-programmable input/output dividers, feedback topology, and output inversions via flash memory.
• Twelve LVTTL outputs grouped in two banks (CLKA/CLKB) with selectable drive strengths and three-state capability.
• Dual reference inputs (REF1, REF2) with glitch-free switching controlled by the REFSEL pin.
• Auto power-down circuit reduces current draw to less than 50 µA during reference clock failure.

Clock Buffers, Drivers Applications

• High-speed clock distribution for ASICs and microprocessors.
• Systems requiring multiple clock domains with split voltage levels.
• Glitch-free clock source selection and redundancy circuits.

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix '002' corresponds to specific factory programming configurations as defined by Cypress. Confirm the package type matches the 28-pin SSOP specification. Ensure the temperature range aligns with commercial requirements (0 °C to 70 °C). Check for lead-free compliance status if required by assembly standards.

Clock Buffers, Drivers Selection Notes

Select this component when a fixed-function buffer is insufficient due to varying divider ratios or output inversion needs. The CY23FP12 allows customization of up to four distinct personalities using S1/S2 control bits. Ensure the design accommodates the need for external programming tools like the CY3672-USB kit before deployment.

Clock Buffers, Drivers Part Context

This part belongs to the CY23FP12 family of 200 MHz field-programmable zero delay buffers. It shares functional similarities with other Cypress clock drivers but distinguishes itself through its fully programmable architecture. The OXC suffix indicates a commercial temperature range and 28-pin SSOP packaging.

Clock Buffers, Drivers Replacement Considerations

Direct replacements must support field-programmability and similar output counts. Consider the CY23FP12 variants with different temperature ratings (e.g., OXI for industrial) or packaging options if available. Verify compatibility with existing programmer software and hardware interfaces.
