The device is used for PC or embedded systems to substantially reduce Electro- magnetic Interference (EMI). The PI6CFGL202B provides two differential (HCSL) or LVDS spread spectrum outputs. The PI6CFGL202B is configured to se- lect spread and clock selection. Using Pericom's patented Phase- Locked Loop (PLL) techniques, the device takes a 25MHz crystal input and produces two pairs of differential outputs (HCSL) at 25MHz, 100MHz, 125MHz and 200MHz clock frequencies. It also provides spread selection of -0.5%, -0.75%, and no spread. Features Î Î PCIe® 3.0, 2.0 and 1.0 compliant Î Î LVDS compatible outputs Î Î Supply voltage of 3.3V ±10% Î Î 25MHz crystal or clock input frequency Î Î Low power consumption with independent output power supply 1.05V to 3.3V Î Î Jitter 35ps cycle-to-cycle (typ) Î Î Spread of -0.5%, -0.75%, and no spread Î Î Industrial temperature range Î Î Spread Bypass option available Î Î Spread and frequency selection via external pins Î Î Packaging: (Pb-free and Green) à 16-pin TSSOP (L16) Low Power PCIe 3.0 Clock Generator with 2 HCSL Outputs 15-0025 |
