5P49V5901B045NLGI8

Clock Generators, PLLs, Frequency Synthesizers Overview

The 5P49V5901B045NLGI8 is a VersaClock 5 low-power programmable clock generator manufactured by Renesas Electronics. It features a single PLL capable of generating up to four independent output frequencies with a total of seven differential outputs and one reference LVCMOS output. The device supports multiple differential I/O standards, including LVDS, LVPECL, and HCSL, with individual frequency programming for each output pair. It incorporates four fractional output dividers (FODs) with independent spread spectrum capability and stores up to four configurations in OTP memory. The maximum output frequency reaches 350MHz, with input frequencies up to 200MHz.
