PL123S-05SC-R

Clock Generators, PLLs, Frequency Synthesizers Overview

The PL123S-05SC-R is a low skew, zero delay buffer manufactured by Microchip Technology (originally Micrel). It provides one input reference frequency to five buffered clock outputs. The device operates within a frequency range of 10 MHz to 134 MHz and requires a 3.3V supply voltage with ±10% tolerance. It features spread-spectrum modulation compatibility to reduce electromagnetic interference. The component is housed in an 8-pin SOP package and supports commercial temperature operation from 0°C to 70°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Zero delay buffer architecture with input-to-output skew less than ±100 ps
• Spread-spectrum compatible for EMI reduction
• Standard drive strength of 8 mA per output
• PLL bypass mode available via S1/S2 selector inputs

Clock Generators, PLLs, Frequency Synthesizers Applications

• High-speed clock distribution systems
• Systems requiring spread-spectrum clocking for FCC compliance
• Low jitter clock buffering for digital circuits

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the ordering suffix 'R' indicates tape and reel packaging. Confirm the 'C' suffix denotes the commercial temperature range (0°C to 70°C). Ensure the base part number matches the 5-output configuration (PL123S-05) rather than the 9-output variant. Check for RoHS compliance status as specified in the manufacturer's documentation.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single clock source needs to be distributed to five loads with minimal skew. The standard 8 mA drive strength is suitable for typical CMOS loads. For higher drive requirements, consider the PL123S-05H variant which offers 12 mA. Ensure the application does not require 5V input tolerance, as this device is strictly for 3.3V operation.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the PL123S family of spread-compatible low skew zero delay buffers. The PL123S-05 variant specifically provides five outputs, whereas the PL123S-09 provides nine. The 'SC' designation identifies the 8-pin SOP package type for the -05 model. The device was originally released by Micrel Inc., which was later acquired by Microchip Technology.
