Multiplier Zero Delay Buffer
MK2302S-01is high performance Zero Delay Buffer (ZDB) which integrates ICS' proprietary analog/digital Phase Locked Loop (PLL) techniques. chip part ICS' ClockBlocksfamily designed performance upgrade meet today's higher speed lower voltage requirements. zero delay feature means that rising edge input clock aligns with rising edges both output clocks, giving appearance delay through device. There outputs chip, being low-skew divide other output. MK2302S-01 ideal synchronizing outputs large variety systems, from personal computers data communications graphics/video. allowing off-chip feedback paths, device eliminate delay through other devices.

External Components
MK2302S-01 requires 0.01µF decoupling capacitor connected between GND. must connected close part minimize lead inductance. external power supply filtering required this device. series terminating resistor used next each output pin. Using CLK1 feedback will always result synchronized rising edges between ICLK CLK1. However, CLK2 could falling edge compared with ICLK. recommends using CLK2 feedback whenever possible. This will synchronize rising edges three clocks.
