描述
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
特性
- 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 a 48-pin TSSOP or 48-pin 7mm x 7mm VFQFPN with 0.5mm pad pitch
- Pb-free, RoHS-compliant
