NOTICE - The following device(s) are recommended alternatives:

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.


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 at12M or 24M
 

Features

  • Replaces 11 crystals, 2 oscillators and 3 clock generators; lowers cost, power and area
  • Use external reference crystal
  • 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
