PCS3P6100a reduces electromagnetic interference (emi) at the clock source, allowing system wide reduction of emi of all clock dependent signals. PCS3P6100a allows significant system cost savings by reducing the number of circuit board layers, ferrite beads, and shielding that are traditionally required to pass emi regulations. the supply voltage of the device is 3.3v / 2.5v. it has two spread selection pins, ss1% and ss2%. refer to the spread deviation selection table for details. the device is available in 6l-tsot23 package. application PCS3P6100a is targeted for use in display systems. blo ck diagram vss vdd clkin modout pll ss1% ss2%
