PI6C557-03AQE

Pb A product Line of Diodes Incorporated Lead-free Green PI6C557-03A PCIe 2.0 Clock Generator with 2 HCSL Outputs Features Description ÎÎPCIe® 2.0 compliant The PI6C557-03A is a spread spectrum clock generator compliant to PCI Express® 2.0 and Ethernet requirements. The device is used for PC or embedded systems to substantially reduce Electromagnetic Interference (EMI). àà Phase jitter - 2.1ps RMS (typ) ÎÎLVDS compatible outputs ÎÎSupply voltage of 3.3V ±10% ÎÎ25MHz crystal or clock input frequency The PI6C557-03A provides two differential (HCSL) or LVDS spread spectrum outputs. The PI6C557-03A 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 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. ÎÎHCSL outputs, 0.8V Current mode differential pair ÎÎJitter 35ps cycle-to-cycle (typ) ÎÎSpread of -0.5%, -0.75%, and no spread ÎÎIndustrial temperature range ÎÎSpread Bypass option available ÎÎSpread and frequency selection via external pins ÎÎTotally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) ÎÎHalogen and Antimony Free. “Green” Device (Note 3) ÎÎPackaging: (Pb-free and Green) àà 16-pin TSSOP (L16) àà 16-pin QSOP (Q16) Block Diagram Pin Configuration (16-Pin TSSOP) VDD 2 SS1:SS0 S1:S0 2 CLK0 Control Logic 2 CLK0 Phase Lock Loop CLK1 X1/CLK 25 MHz crystal or clock X2 Pulling Capacitors CLK1 Crystal Driver 2 S0 1 16 VDDX S1 2 15 CLK0 SS0 3 14 CLK0 X1/CLK 4 13 GNDA X2 5 12 VDDA OE 6 11 CLK1 GNDX 7 10 CLK1 SS1 8 9 IREF RR GND OE Notes:       1.
