IDT6V49205A REV Q 112316

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

• Integrated terminations on LP-HCSL PCIe outputs;

eliminate 24 resistors, saving 41mm

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

• Packaged as 48-pin TSSOP, Pb-free, RoHS compliant
