NB3L853141DTG

Clock Buffers, Drivers Overview

The NB3L853141 is a low skew 1:5 LVPECL clock fanout buffer designed for high-speed distribution. It features a multiplexed input accepting either differential (CLK0/CLK0) or single-ended (CLK1) signals, selectable via the SEL pin. The device provides five differential LVPECL outputs with a maximum frequency of 700 MHz and a typical output-to-output skew of 30 ps. Operating on a 2.375 V to 3.8 V supply, it includes synchronous enable control to prevent runt pulses. Key electrical parameters include a maximum propagation delay of 1.5 ns and an additive phase jitter of 0.057 ps RMS.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'DTG' corresponds to the TSSOP-20 package in lead-free configuration. Confirm that the required quantity aligns with the standard shipping unit of 75 units per rail for this specific part number variant.

Clock Buffers, Drivers Selection Notes

Select this component when distributing a single clock source to five LVPECL loads requiring minimal skew. Ensure the input source supports the selected mode (differential or single-ended) and that the power supply voltage remains within the 2.375 V to 3.8 V range for proper operation.

Clock Buffers, Drivers Part Context

This device belongs to the NB3L8531 family of fanout buffers. It serves as a high-performance solution for clock distribution networks where signal integrity and precise timing alignment are critical requirements for system synchronization.
