描述
The 6P41505 is a system clock generator intended for 7A1000 and L3A3000 Loongson CPU platforms. The device uses a low-cost 25MHz crystal as an input and can generate the following frequencies:
- 5 × CMOS clocks for system reference
- 12 × 100MHz LP-HCSL with PCIe Gen 3 performance
- 1 × 200MHz LVDS for HT reference
The 6P41505 system clock generator is intended for high-performance consumer, networking, industrial, computing, and data-communications applications.
