LMK00725PWR

Clock Buffers, Drivers Overview

The LMK00725PWR is a low skew, high-performance clock fanout buffer manufactured by Texas Instruments. It distributes up to five 3.3V differential LVPECL outputs from one of two selectable inputs. The device supports differential or single-ended input signals including LVPECL, LVDS, HCSL, SSTL, LVHSTL, and single-ended signals. Key electrical parameters include a maximum output frequency of 650 MHz, a typical additive jitter of 43 fs RMS at 312.5 MHz, and a maximum propagation delay of 0.37 ns. It operates on a 3.3V ± 5% power supply within an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'PWR' corresponds to the TSSOP-20 package in a large tape-and-reel carrier containing 2500 units. Confirm RoHS compliance and lead finish specifications via the manufacturer's packaging addendum. Ensure the procurement channel provides valid production data documentation for the specific batch.

Clock Buffers, Drivers Selection Notes

Select this component when distributing a single clock signal to five downstream LVPECL loads requiring low skew and minimal added jitter. Verify that the input source meets the recommended slew rate of 3 V/ns or greater to maintain optimal noise floor performance. Ensure the system power supply can provide the required current while maintaining voltage stability within the 3.135 V to 3.465 V operating range.

Clock Buffers, Drivers Part Context

The LMK00725 belongs to the LMK00725 series of clock buffers. The 'PWR' suffix specifically denotes the tape-and-reel packaging format, distinguishing it from the tube-packaged 'PW' variant. Both variants share identical electrical characteristics and pinouts but differ in shipping quantity and handling requirements.
