5U49319中文资料Very Low Power Clock for Freescale MCU’S数据手册Renesas规格书

描述 Description

The IDT5U49319 is a very low power clock for Freescale P10xx and P20xx MCU’s. It uses a 1.5V core and Low-Power HCSL (LP-HCSL) differential outputs for minimal power consumption. The SATA and SRC outputs are PCIe Gen1/2 compatible.

特性 Features

·Various outputs are configurable to run in power down; supports Wake_On_LAN
·FPGA clock frequency is selectable via SMBus; allows low-power system standby
·Strapping pin sources SRC outputs from either spreading or non-spreading PLL; maximum system flexibility
·FLEX clock is pin selectable to be FPGA clock or USB PHY clock; maximum system flexibility
·TEST pin tri-states all outputs; speeds up board test
·External 25MHz crystal; supports tight ppm
·OE# pins; support SRC power management
·Low power differential clock outputs; reduced power and board space
·Differential outputs internally terminated to 100ohm differential impedance; reduced board space
·Space-saving 7x7mm 48-pin VFQFPN with 0.5mm pad pitch; reduced board space without the need for fine pitch assembly techniques
