PI6C4911506LIEX

Clock Buffers, Drivers Overview

The PI6C4911506 is a high-performance fanout buffer featuring six LVPECL outputs, supporting frequencies up to 1.5 GHz. It accepts a single differential input and delivers ultra-low additive phase jitter of less than 0.03 ps (typical) at 156.25 MHz with a 12 kHz to 20 MHz integration range. The device operates on a 2.5 V or 3.3 V supply within an industrial temperature range of -40°C to +85°C. Propagation delay is typically under 800 ps, and it is housed in a TSSOP-20 package.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'LIEX' corresponds to the Tape & Reel packaging variant as specified in the datasheet. Confirm that the component meets Pb-free and Green manufacturing standards. Ensure the selected package matches the TSSOP-20 footprint requirements for the target PCB design.

Clock Buffers, Drivers Selection Notes

Select this component when distributing low jitter LVPECL clocks to multiple destinations in high-speed networking or telecom applications. Ensure the system supports 2.5 V or 3.3 V power supplies. Verify that the input signal interface is compatible with the differential LVPECL input configuration provided by the REF_IN+ and REF_IN- pins.

Clock Buffers, Drivers Part Context

The PI6C4911506 belongs to the PI6C49115xx series of high-performance fanout buffers manufactured by Diodes Incorporated (formerly Pericom). This series is designed for applications requiring precise clock distribution with minimal added jitter. The specific model provides six outputs, distinguishing it from other variants in the family that may offer different output counts.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative devices only if they match the 6-output LVPECL configuration, 1.5 GHz frequency support, and TSSOP-20 package constraints.
