The PT7C4511 is a high-performance frequency multiplier that integrates Analog Phase Lock Loop techniques. 

The PT7C4511 is the most cost-effective way to generate a high-quality, high-frequency clock output from a lower frequency crystal or clock input. It is designed to replace crystal oscillators in most electronic systems, clock multiplier, and frequency translation.

Using Phase-Locked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 200MHz.

The PT7C4511 is a high-performance frequency multiplier, different popular multiplication factors, allowing one chip to output many common frequencies.

The device also has an Output Enable pin that tri-states the clock output when the OE pin is taken low. This product is intended for clock generation and frequency translation with low output jitter (variation in the output period). 


  • Zero ppm multiplication error
  • Input crystal frequency of 5-30 MHz
  • Input clock frequency 1-50 MHz
  • Peak to Peak jitter less than 200ps over 200ns interval (100-200 MHz)

  • 9 selectable frequencies controlled by S0, S1 pins
  • Operating voltages of 3.0 to 5.5V
  • Tri-state output for board level testing
  • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. "Green" Device (Note 3)
  • For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ 
  • Package: 8-pin, SOIC
