PL135-27GI-R

Clock Buffers, Drivers Overview

The PL135-27GI-R is a low-power oscillator fanout buffer manufactured by Micrel, now part of Microchip Technology. It accepts a fundamental crystal input between 10MHz and 40MHz and generates two LVCMOS outputs at the same frequency. The device operates on a single supply voltage ranging from 1.62V to 3.63V. Key electrical characteristics include an output drive strength of 8mA, a maximum output-to-output skew of 500ps, and a settling time of 2ms at power-up. It is housed in a compact 2.0mm x 1.3mm DFN-6L package.

Clock Buffers, Drivers Feature Summary

• Generates two LVCMOS clock outputs with 8mA drive strength
• Operates on a single 1.62V to 3.63V power supply
• Housed in a small 2.0mm x 1.3mm DFN-6L package

Clock Buffers, Drivers Applications

• High-performance, low-power embedded systems
• Small form-factor consumer electronics
• Industrial control applications requiring precise timing

Clock Buffers, Drivers Procurement Notes

Verify that the component is sourced from authorized distributors to ensure authenticity. Confirm the specific suffix 'GI' corresponds to the -40°C to +85°C industrial temperature range as defined in the ordering information. Check for RoHS compliance status and verify the package marking 'J27' matches the physical unit received.

Clock Buffers, Drivers Selection Notes

Select the PL135-27GI-R when an industrial temperature range (-40°C to +85°C) is required. Choose this over the 'GC' variant if operation outside the commercial range is necessary. Ensure the application utilizes a fundamental crystal within the 10MHz to 40MHz range and requires LVCMOS outputs rather than other logic families.

Clock Buffers, Drivers Part Context

This component belongs to the PL135 series of oscillator fanout buffers designed by Micrel. The 'GI' suffix specifically denotes the industrial temperature grade (-40°C to +85°C), distinguishing it from the commercial grade 'GC' variant (0°C to +70°C). Both variants share identical electrical specifications and pin configurations.

Clock Buffers, Drivers Replacement Considerations

The PL135-27GC-R is a direct functional substitute with identical electrical parameters, differing only in the operating temperature range (commercial vs. industrial). No other cross-model replacements are documented in the provided datasheet.
