SSDCP1108AF Spectrum Device General Purpose Peak EMI reduction IC General Features ?? ?? ?? ?? ?? ?? ?? ?? ?? 1x, LVCMOS Peak EMI Reduction Incorporates the latest Timing-Safe? technology which allows the spread of analog video signal Input frequency: 1 0MHz - 35MHz @ 2.5V 1 0MHz - 40MHz @ 3.3V Output frequency : 1 0MHz - 35MHz @ 2.5V 1 0MHz - 40MHz @ 3.3V Analog Deviation Selection Spread Spectrum Enable/Disable Supply Voltage: 2.5V±0.2V 3.3V±0.3V 8pin TDFN(2X2) COL Packages Commercial temperature range DC coupled to XIN/CLKIN) and locks on to it delivering a 1x modulated clock output. SSDCP1108AF has a SSON pin for enabling and disabling Timing-Safe?? Spread Spectrum function. SSDCP1108AF has an SSEXTR pin to select different deviations depending upon the value of an external resistor connected between SSEXTR and GND. Charge Pump (CP) control selects one of the two different Charge Pump current settings. SSDCP1108AF operates from a 3.3V/2.5V supply, and is available in an 8 pin TDFN(2X2) COL packages, over Commercial temperature range. Functional Description SSDCP1108AF is a versatile, 3.3V/2.5V Peak EMI reduction IC. SSDCP1108AF accepts an input clock either from a fundamental Crystal or from an external reference (AC or ??
