描述 Description

The 6V49205B is a main clock for Freescale P10xx and

P20xx-based systems. It has a selectable System CCB clock

and 2 DDRCLK speeds – 100M or 66.66M. The 6V49205B

also provides LP-HCSL PCIe outputs for low power and

reduced board space.

Typical Applications

System Clock for Freescale P10xx and P20xx-based designs

特性 Features

? Replaces 11 crystals, 2 oscillators and 3 clock generators;

lowers cost, power and area

? Integrated terminations on LP-HCSL PCIe outputs;

eliminate 24 resistors, saving 41mm2 of board area

? Industrial temperature range operation; supports

demanding environmental conditions

? Advanced 3.3V CMOS process; high-performance,

low-power

? Supports independent spread spectrum on

Sys_CCB/DDRCLK and PCIe outputs

? Available in 48-pin TSSOP and space-saving 7 x 7 mm

48-pin VFQFPN with 0.5mm pad pitch; reduced board

space without the need for fine-pitch assembly techniques
