PL135-37SC-R

Clock Buffers, Drivers Overview

The PL135-37SC-R is a low-power oscillator fanout buffer manufactured by Micrel Inc. It accepts a fundamental crystal input between 10MHz and 40MHz and generates three LVCMOS outputs at the same frequency. The device operates on a single power supply ranging from 1.62V to 3.63V. Key electrical characteristics include a maximum output drive strength of 12mA, an output-to-output skew of 250ps, and a typical dynamic supply current of 4mA at 3.3V and 25MHz. The component is housed in an SOP-8L package.

Clock Buffers, Drivers Procurement Notes

Verify that the source material identifies Micrel Inc. as the manufacturer, as the model number indicates Microchip Technology ownership. Confirm the package type is SOP-8L and the temperature range is Commercial (0°C to 70°C). Ensure the ordering suffix 'R' corresponds to Tape and Reel shipping options as specified in the datasheet.

Clock Buffers, Drivers Selection Notes

Select this component when a 1:3 fanout buffer is required for fundamental crystals operating between 10MHz and 40MHz. It is suitable for applications needing low power consumption and LVCMOS compatibility. Verify that the system voltage falls within the 1.62V to 3.63V range and that the SOP-8L package fits the PCB layout constraints.

Clock Buffers, Drivers Part Context

The PL135-37 series is designed for high-performance, low-power applications. The PL135-37SC-R specifically denotes the SOP-8L package variant with commercial temperature grading and tape-and-reel packaging. This part is part of a family offering various fanout configurations and packages.

Clock Buffers, Drivers Replacement Considerations

Check for direct replacements within the PL135-37 family or other Micrel/Microchip oscillator buffers. Ensure any substitute supports the 10MHz to 40MHz fundamental crystal input range and provides compatible LVCMOS outputs.
