5P49V6965 - Programmable VersaClock® Clock Generator
Pin-pin compatible with additional functionality and design margin

The IDT 5P49V5923 is low-power programmable clock generator with best-in-class jitter performance and design flexibility with LVCMOS outputs capable of generating any output frequency. The 5P49V5923 is 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 IDT’s fifth generation of programmable clock technology (VersaClock 5). The frequencies are generated from a single reference clock or crystal input. A glitchless manual switchover function allows one of the redundant clock inputs to be selected during normal operation.

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.


  • 3 LVCMOS outputs, including 1 reference output
  • In-system programmable with 2 independent output frequencies
  • Up to 200 MHz input/output frequencies
  • Also supports crystal input
  • Stores 4 different configurations in OTP non-volatile memory
  • < 100 mW core power (at 3.3V)
  • < 0.7 ps RMS phase jitter (typ)
  • Meets PCIe® Gen1/2/3, USB 3.0, 1/10 GbE clock requirements
  • 1.8 / 2.5 / 3.3V core and output voltages
  • 4x4 mm 24-ld VFQFPN
  • -40° to +85°C operating temperature range
