VersaClock® 5 Low Power Programmable Clock Generator

NOTICE - The following device(s) are recommended alternatives:
The 5P49V5907 is a programmable clock generator intended for high performance consumer, networking, industrial, computing, and data communications applications. Configurations may be stored in on-chip One-Time Programmable (OTP) memory or changed using I2C interface. This is IDTs fifth generation of programmable clock technology (VersaClock® 5). The frequencies are generated from a single reference clock or crystal.
Two select pins allow up to 4 different configurations to be programmed and accessible using processor GPIOs or bootstrapping. The different selections may be used for different operating modes (full function, partial function, partial power-down), regional standards (US, Japan, Europe) or system production margin testing. The device may be configured to use one of two I2C addresses to allow multiple devices to be used in a system. The device is packaged in a 40-pin 5mm x 5mm VFQFPN (NDG40), with an industrial operating temperature of -40 to +85°C.


  • Generates up to four independent output frequencies with a total of 7 differential outputs and one reference LVCMOS output
  • Supports multiple differential output I/O standards:
    • Three universal outputs pairs with each configurable as one differential output pair (LVDS, LVPECL or regular HCSL) or two LVCMOS outputs. Frequency of each output pair can be individually programmed
    • Four copies of Low Power HCSL (LP-HCSL) outputs
  • Meets PCIe® Gen1/2/3, USB 3.0, 1/10 GbE clock requirements
  • <0.7 ps RMS typical phase jitter on outputs
  • Four fractional output dividers (FODs)
  • Independent Spread Spectrum capability from each fractional output divider (FOD)
  • Stores 4 different configurations in OTP non-volatile memory
  • Input frequency ranges up to 200 MHz
  • Output frequency ranges up to 350 MHz
  • Progammable loop bandwidth and crystal load capcaitance
  • 1.8 / 2.5 / 3.3V core and output voltages
  • Supported by IDT Timing Commander™ software tool
