Clocks & Timing

Overview

The 5P49V6968 is a member of IDT's VersaClock® 6E programmable clock generator family. The 5P49V6968 is intended for high-performance consumer, networking, industrial, computing, and data-communications applications. The reference clock can come from one of the two redundant clock inputs. A glitchless manual switchover function allows one of the redundant clocks to be selected during normal operation.
 
Configurations may be stored in on-chip One-Time Programmable (OTP) memory or changed using I²C interface.

    VersaClock® 6E - High-performance Programmable Clock Generator

    The VersaClock® 6E programmable clock generator devices offer a combination of low power, flexibility and performance for a wide range of applications. These features make it ideal for simplifying system design by replacing multiple discrete timing components and reducing bill of materials (BOM). The VersaClock 6E supports operating voltages from 1.8 to 3.3 V, differential (LVPECL/HCSL/LVDS/LP-HCSL) and LVCMOS output types, and fractional dividers to accurately generate virtually any frequency. Products satisfy system requirements from oscillator replacement to PCIe® Gen 1/2/3 and to communications applications, while consuming very little power.
