PL133-97QI-R

Clock Buffers, Drivers Overview

The PL133-97QI-R is a low-power DC to 150MHz 1:9 fanout buffer manufactured by Microchip Technology. It accepts a reference clock input and provides nine buffered LVCMOS outputs with an 8mA drive strength. The device operates within a supply voltage range of 1.62V to 3.63V, supporting full performance up to 150MHz at 2.5V/3.3V and up to 67MHz at 1.8V. Key electrical parameters include a maximum propagation delay of 9.2ns, output-to-output skew less than 250ps, and typical additive phase jitter of 60fs RMS. It is housed in a 16-pin QFN package and rated for industrial temperatures from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Provides 1:9 LVCMOS fanout buffering for clock signals ranging from DC to 150MHz.
• Features low additive phase jitter (60fs RMS) and output-to-output skew (<250ps).
• Includes a dedicated free-running output (CLK8) that remains active when the Output Enable (OE) pin is pulled low.
• Operates on a single supply voltage between 1.62V and 3.63V.

Clock Buffers, Drivers Applications

• High-performance portable applications requiring low power consumption.
• Clock distribution networks for systems utilizing multiple CMOS components.
• Small form factor designs necessitating compact QFN packaging.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) as opposed to the Commercial variant. Confirm the 'R' suffix indicates Tape & Reel packaging. Ensure the source document matches the PL133-97 datasheet for accurate Micrel/Microchip specifications.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:9 fanout ratio is required with minimal signal degradation. Consider the 1.8V operation limit of 67MHz if using lower supply voltages. Ensure PCB layout adheres to the recommended trace lengths and decoupling capacitor placement near VDD pins to maintain signal integrity.

Clock Buffers, Drivers Part Context

This part belongs to the PL133 series of low-power fanout buffers originally developed by Micrel, now under Microchip Technology. The PL133-97 specifically offers a 1:9 split, distinguishing it from other series members like the PL133-21 (1:2) or PL133-37 (1:3).

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify compatibility with existing 1:9 LVCMOS buffers if cross-referencing is necessary.
