PL133-67OI-R

Clock Buffers, Drivers Overview

The PL133-67OI-R is a low-power 1:6 LVCMOS fanout buffer IC manufactured by Microchip Technology (originally Micrel). It accepts a reference clock input from DC to 150 MHz and provides six buffered outputs with an output drive strength of 8 mA. The device operates on a supply voltage (VDD) ranging from 2.25 V to 3.63 V. Key electrical specifications include a maximum propagation delay of 9.2 ns, output-to-output skew less than 250 ps, and additive phase jitter of 60 fs RMS at 100 MHz. It is housed in a 16-pin TSSOP package and supports an industrial operating temperature range of -40°C to 85°C.

Clock Buffers, Drivers Feature Summary

• 1:6 LVCMOS fanout buffer supporting DC to 150 MHz input frequencies
• Low additive phase jitter of 60 fs RMS (12 kHz to 20 MHz offset)
• Output-to-output skew guaranteed less than 250 ps
• Tri-state output control via OE pin with internal 130 kΩ pull-up

Clock Buffers, Drivers Applications

• High-performance clock distribution networks
• Portable applications requiring low power consumption
• Small form factor systems needing low input-output delay

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'I' confirms the Industrial temperature range (-40°C to 85°C) and '-R' indicates Tape & Reel packaging. Confirm the manufacturer origin as Micrel/Microchip Technology. Ensure the datasheet revision matches the specific component lot for accurate electrical characterization data.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source needs to drive up to six loads with minimal skew. Ensure the load capacitance requirements are met: 30 pF below 100 MHz, 10 pF between 100 MHz and 134 MHz, and 5 pF above 134 MHz. Verify that the system power supply remains within the 2.25 V to 3.63 V operational window.

Clock Buffers, Drivers Part Context

The PL133-67 belongs to the PL133 series of low-power fanout buffers. The 'OI' suffix denotes the Industrial temperature grade and TSSOP-16 package, while the '-R' suffix specifies tape and reel packaging. This variant is designed for applications requiring high signal integrity and low noise performance compared to standard CMOS buffers.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical parameters against alternative 1:6 fanout buffers if sourcing changes occur.
