6V49205A Block Diagram
Description
The 6V49205A is a main clock for Freescale P10xx and P20xx-based systems. It has a selectable system CCB clock and a 66.66MHz DDRCLK. The 6V49205A also provides LP-HCSL PCIe outputs for low power and reduced board space.
Output Features
- 1 – Sys_CCB 3.3V LVCMOS output at 100M/83.33M/80M/66.66M
- 1 – DDRCLK 3.3V LVCMOS output at 66.66M
- 1 –125M 3.3V LVCMOS output
- 6 – LP-HCSL PCIe pairs selectable at 100M or 125M
- 6 – 25MHz 3.3V LVCMOS outputs
- 2 – 2.048M 3.3V LVCMOS outputs
- 2 – USB 3.3V LVCMOS outputs at 12M or 24M

Can a 3.3V signal from a 25 MHz crystal oscillator be used as an input signal to the 6V49205 family (6V49205A & 6V49205B), instead of a 25 MHz crystal?
Yes. The X1 pin can be driven directly from a quartz crystal clock oscillator. We recommend using a 33 ohm series resistor on the oscillator output. Do not use MEMS or programmable clock oscillators. The X2 (Xout) pin needs to be left floating. For other questions not addressed by the ...
