Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against official Cypress documentation to confirm pinout and electrical characteristics. Ensure the 32-TQFP package dimensions match the target PCB footprint. Confirm that the required supply voltage aligns with either the 2.5V or 3.3V operational range specified in the datasheet before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a low-skew clock distribution solution is required for LVCMOS loads driven by LVPECL sources. Verify that the system power supply falls within the specified 2.375V–2.625V or 3.135V–3.465V windows. Ensure the thermal environment remains within the -40°C to 85°C industrial temperature range for reliable operation.

Clock Buffers, Drivers Part Context

This part belongs to the CY29658 series of clock buffers. It serves as a critical interface between high-speed differential clock sources and multiple single-ended logic loads.
