The 844201I-45 is a PCI Express®TM Clock Generator. The 844201I-45 can synthesize 100MHz or 125MHz reference clock frequencies with a 25MHz crystal. The 844201I-45 has excellent phase jitter performance and is packaged in a small 16-pin VFQFN, making it ideal for use in systems with limited board space.

特性
