The Renesas Electronics 5P49V6901 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 sixth generation of programmable clock technology (VersaClock® 6). The frequencies are generated from a single reference clock. 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.

4 universal outputs LVPECL, LVDS, HCSL - or 8 LVCMOS outputs
In-system programmable with 4 independent Output Frequencies
Up to 350 MHz input/output frequencies
Also supports crystal input
Stores 4 different configurations in OTP non-volatile memory
