REN6V49205BNLGI8
Overview
The 6V49205BNLGI8 is a specialized system clock generator designed primarily for Freescale P10xx and P20xx series processors. It operates on a 3.3V supply and provides a comprehensive suite of buffered clock outputs including CPU, PCIe, DDR, and Ethernet frequencies from a single crystal input. This 48-pin VFQFPN device simplifies timing architecture by replacing multiple discrete crystal oscillators in networking and industrial computing designs.
Why Choose This Part
This integrated solution reduces PCB footprint and BOM complexity by consolidating several frequency domains into one chip. It features SMBus programmability for output management and meets the stringent jitter requirements of high-speed serial interfaces like PCIe.
Applications
Getting Started
Engineers should consult the Freescale processor hardware specification to determine the required strap configurations for clock ratios. Design the PCB with a 25MHz crystal close to the X1/X2 pins and use the SMBus interface for software-based output enable/disable control. Ensure the thermal pad of the 7x7mm VFQFPN package is properly soldered to the ground plane for stable operation at the maximum 155mA current draw.
