PL133-27GI

Clock Buffers, Drivers Overview

The PL133-27GI is a low-power, 1:2 inverting fanout buffer IC manufactured by Microchip Technology. 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 1.62V to 3.63V, supporting standard 1.8V, 2.5V, or 3.3V ±10% rails. It features extremely low additive jitter (typical 130 fs at 26 MHz) and an output drive strength of 8 mA. The component is housed in a compact 6-lead TDFN package measuring 2 mm x 1.3 mm x 0.6 mm and supports both LVCMOS and sine-wave input signals via internal AC coupling.

Clock Buffers, Drivers Feature Summary

• 1:2 Inverting Fanout Buffer with 1 MHz to 150 MHz operating frequency range
• Extremely low additive phase jitter (typical 130 fs at 26 MHz)
• Supports LVCMOS and Sine-Wave inputs with internal AC coupling
• Low current consumption (typical 1.3 mA at 2.5V, 25 MHz)

Clock Buffers, Drivers Applications

• High-performance, low-power embedded systems requiring clock distribution
• Small form-factor applications with strict space constraints
• Systems utilizing 1.8V, 2.5V, or 3.3V power supplies

Clock Buffers, Drivers Procurement Notes

Verify that the ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C). Confirm the specific packaging configuration required for production, as the base part number may be available in bag or tape-and-reel formats. Ensure the design accounts for the inverting nature of the CLK0 and CLK1 outputs relative to the FIN input.

Clock Buffers, Drivers Selection Notes

Select the PL133-27GI when an industrial temperature rating is required alongside low-power clock buffering. This model provides two inverted outputs suitable for differential-like signaling or dual-clock domain distribution. Ensure the application frequency does not exceed 150 MHz at 2.5V/3.3V or 65 MHz at 1.8V operation.

Clock Buffers, Drivers Part Context

The PL133-27GI belongs to the PL133-27 family of low-power fanout buffers. The 'G' suffix indicates the 6-lead TDFN package, while 'I' specifies the -40°C to +85°C industrial temperature grade. Other variants include the commercial grade (C) and different packing options (R for reel).

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include PL133-27GC (Commercial Temp) or PL133-27GI-R (Reel Pack). Verify that any substitute maintains the 1:2 ratio, inverting logic, and compatible package dimensions.
