ICS810001-21 FEMTOCLOCKS™ DUAL VCXO VIDEO PLL FEATURES Accepts various HD and SD references including hsync, transport and pixel clock rates Outputs HD and SD pixel rates One LVCMOS/LVTTL PLL clock output Two selectable LVCMOS/LVTTL input clocks LVCMOS input select lines VCXO PLL bandwidth can be optimized for jitter attenuation and reference tracking FemtoClock frequency multiplier provides low jitter, high frequency output FemtoClock range: 560MHz - 700MHz RMS phase jitter @148.3516484MHz, using a 26.973027MHz crystal (12kHz - 20MHz): 0.81ps (typical) 3.3V supply voltage 0°C to 70°C ambient operating temperature GENERAL DESCRIPTION The ICS810001-21 is a member of the HiperClockS™ family of high performance clock HiPerClockS™ solutions from ICS. The ICS810001-21 is a PLL based synchronous clock generator that is optimized for digital video clock jitter attenuation and frequency translation. The device contains two internal frequency multiplication stages that are cascaded in series. The first stage is a VCXO PLL that is optimized to provide reference clock jitter attenuation, and to support the complex PLL multiplication ratios needed for video rate conversion. The second stage is a FemtoClock frequency multiplier that provides the low jitter, high frequency video output clock. IC S Preset multiplication ratios are selected from internal lookup tables using device input selection pi...
