CY7B991V-2JXCT

Overview

The CY7B991V-2JXCT is a zero-delay programmable PLL clock buffer from Infineon Technologies' RoboClock series. It operates on a single 3.3V supply (2.97V to 3.63V) and supports output frequencies up to 80 MHz. The device features an 8:8 fan-out ratio with LVTTL outputs and accepts a 3-state input. Packaged in a surface-mount 32-LCC (J-Lead) PLCC case, it functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Zero-delay programmable PLL architecture for precise clock synchronization
• 8:8 fan-out ratio converting one input to eight LVTTL outputs
• Supports maximum operating frequency of 80 MHz
• 3-state input capability for bus isolation

Applications

• High-performance digital system clock distribution
• FPGA and ASIC clock buffering
• Telecommunications equipment timing circuits

Procurement Notes

Verify the TR package designation against specific handling requirements. Confirm RoHS compliance status through official datasheets as local listings may vary. Ensure ESD precautions are observed during storage and assembly due to moisture sensitivity classification.

Selection Notes

Select this component when an 8:8 LVTTL fan-out with zero-delay characteristics is required at frequencies up to 80 MHz. Compare against non-zero-delay buffers if propagation delay tolerance exists. Verify voltage compatibility with the 2.97V–3.63V supply range.

Part Context

This part belongs to the RoboClock family of programmable clock generators. It serves as a buffer driver solution for systems requiring jitter attenuation and clock skew minimization. The suffix 'TR' indicates tape and reel packaging for automated assembly.

Replacement Considerations

Check for direct pin-compatible substitutes within the same RoboClock series. Verify electrical parameters such as supply voltage and output logic levels before substitution.
