PI6C4921506LIE

Clock Buffers, Drivers Overview

The PI6C4921506LIE is a high-performance LVDS fanout buffer manufactured by Diodes Incorporated. It supports output frequencies up to 1.5 GHz and features six differential LVDS outputs driven by a single differential input. The device utilizes proprietary input detection to manage illegal input conditions and includes separate power supplies for core logic (VDD) and I/O levels (VDDO), supporting both 2.5 V and 3.3 V configurations. Key electrical parameters include a maximum propagation delay of 1.2 ns, an output skew of 55 ps, and ultra-low additive phase jitter of less than 0.067 ps RMS at 622.08 MHz.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'LIE' corresponds to the Industrial temperature range (-40°C to +85°C), Pb-free/Green status, and Tape/Reel packaging format as defined in the datasheet. Confirm that the specific package variant matches the 24-pin TSSOP (L) mechanical dimensions provided in the official documentation before finalizing procurement.

Clock Buffers, Drivers Selection Notes

Select this component when distributing high-speed differential clocks to multiple destinations with strict jitter requirements. Ensure the design accommodates separate VDD and VDDO power domains if voltage translation between the input source and downstream LVDS loads is required. Verify that the 24-pin TSSOP footprint aligns with the PCB layout constraints.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49 series of high-performance clock buffers from Diodes Incorporated. It is specifically engineered for networking and telecom applications where signal integrity and low skew are critical. The device replaces older discrete buffering solutions by integrating multiple LVDS drivers into a single compact package.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family should be verified against the official datasheet for pin compatibility and electrical specifications. Cross-model substitution requires confirmation that the alternative device supports the required 1.5 GHz frequency and LVDS output configuration.
