PI49FCT32803QEX

Clock Buffers, Drivers Overview

The PI49FCT32803QEX is a high-speed, low-noise, non-inverting clock buffer manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.97V to 3.63V and supports maximum input frequencies up to 133 MHz. The device features a single input driving seven outputs (1:7 ratio) in a 16-SSOP package. Key electrical parameters include a maximum propagation delay of 2.5 ns, output-to-output skew less than 150 ps, and duty cycle distortion under 300 ps. It functions across an industrial temperature range of -40°C to +85°C with a static current of 30 µA.

Clock Buffers, Drivers Procurement Notes

This component is designated as End-of-Life (EOL) with a discontinuation notification dated March 18, 2026. Verification of final stock availability and last-time-buy deadlines is required before procurement planning. Standard packaging quantities are typically 2,500 units per reel.

Clock Buffers, Drivers Selection Notes

Select the PI49FCT32803QEX when a 1:7 split is required for 3.3V clock signals. Ensure the design accommodates the 16-SSOP footprint. For designs requiring five outputs instead of seven, consider the PI49FCT32802 variant. Verify that the 133 MHz frequency limit meets the system's timing requirements.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of FCT-compatible clock buffers. It shares similar electrical characteristics with the PI49FCT32802 but differs in output count. Both devices target low-jitter applications in the 3.3V domain, offering improved performance over standard logic families regarding skew and noise immunity.

Clock Buffers, Drivers Replacement Considerations

Due to the EOL status, direct substitutes should be evaluated based on pin compatibility and electrical specs. Potential alternatives within the same family include the PI49FCT32802 for reduced output counts. Cross-reference datasheets for equivalent propagation delays and package dimensions.
