DATASHEET
FREESCALE P10XX AND P20XX SYSTEM CLOCK
W/66.66M DDR CLOCK
IDT6V49205A
General Description
The IDT6V49205A is a main clock for Freescale P10xx and
P20xx-based systems. It has a selectable System CCB
clock and a 66.66MHz DDRCLK. The IDT6V49205A also
provides LP-HCSL PCIe outputs for low power and reduced
board space.
Output Features
1 - Sys_CCB 3.3V LVCMOS output @ 100M/83.33M/
80M/66.66M
1 - DDRCLK 3.3V LVCMOS output @ 66.66M
1 - 125M 3.3V LVCMOS output
6 - LP-HCSL PCIe pairs selectable @ 100M or 125M
6 - 25MHz 3.3V LVCMOS outputs
2 - 2.048M 3.3V LVCMOS outputs
2 - USB 3.3V LVCMOS outputs @12M or 24M
Key Specifications
PCIe Gen1-2-3 compliant
<3p rms phase noise on REF outputs
Recommended Application
System Clock for Freescale P10xx and P20xx-based
designs
Features
Replaces 11 crystals, 2 oscillators and 3 clock
generators; lowers cost, power and area
LP-HCSL PCIe outputs reduce termination resistors by
50% while saving 67% power; reduces board area and
power
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
Packaged as 48-pin TSSOP or 48-pin 7x7mm VFQFPN
with 0.5mm pad pitch;– Pb-free, RoHS compliant
