0%, -1.
5%, and no spread • Industrial temperature range • Spread Bypass option available • Spread and frequency selection via external pins • Packaging: (Pb-free and Green) →20-pin, 173-mil wide TSSOP Description The PI6CFGL402B is a spread spectrum clock generator compliant to PCI Express® 3.
0 and Ethernet requirements.
The device is used for PC or embedded systems to substantially reduce Electromagnetic Interference (EMI).
The PI6CFGL402B provides four differential (HCSL) or LVDS spread spectrum outputs.
The PI6CFGL402B is configured to select spread and clock selection.
Using Pericom's patented Phase-Locked Loop (PLL) techniques, the device takes a 25MHz crystal input and produces four pairs of differential outputs (HCSL) at 100MHz and 200MHz clock frequencies.
It also provides spread selection of -0.
5%, -1.
0%, -1.
5%, and no spread.
