PL133-21GC

Clock Buffers, Drivers Overview

The PL133-21 is a low-power, inverting fanout buffer IC designed for high-performance applications. It accepts reference clock inputs from 1 MHz to 150 MHz and produces two inverted LVCMOS outputs of the same frequency. The device operates on a single supply voltage ranging from 1.62 V to 3.63 V, supporting standard 1.8 V, 2.5 V, or 3.3 V systems. It features extremely low additive jitter (typical 0.127 ps at 26 MHz) and an 8 mA output drive strength. The input signal amplitude ranges from 0.8 V to VDD with internal AC coupling. Available in a compact 2 mm x 1.3 mm TDFN package, it supports commercial (-0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Clock Buffers, Drivers Feature Summary

• Two LVCMOS outputs with 1:2 inverting fanout ratio
• Input/Output frequency range of 1 MHz to 150 MHz
• Extremely low additive phase jitter (typical 0.127 ps)
• Single 1.62V to 3.63V power supply operation

Clock Buffers, Drivers Applications

• High performance, low-power small form-factor designs
• Systems requiring precise clock distribution with minimal noise addition
• Applications utilizing LVCMOS or sine-wave input clock signals

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix to confirm packaging and temperature grade. The 'GC' suffix indicates the 6-Lead TDFN package with a commercial temperature range (0°C to +70°C). The '-R' suffix denotes tape and reel packaging containing 3,000 units per reel. Confirm availability through authorized Microchip Technology representatives or sales offices as distribution channels vary.

Clock Buffers, Drivers Selection Notes

Select the PL133-21 when a compact footprint and low power consumption are critical. Ensure the operating voltage falls within the 1.62 V to 3.63 V range. Note that the Output Enable (OE) pin only controls CLK0; CLK1 remains always active. For PCB layout, place decoupling capacitors close to the VDD pin and use series resistors to match trace impedance if necessary.
