Frequency Range 10MHz Output Options: outputs PL123-05 outputs PL123-09 Zero input output delay Optional Drive Strength: Standard (8mA) PL123-05/-09 High (12mA) PL123-05H/-09H 3.3V, ±10% operation Available Commercial Industrial temperature ranges Available 16-Pin TSSOP (PL123-09), 8-Pin (PL123-05) packages
DESCRIPTION
PL123-05/-09 (-05H/-09H High Drive) high performance, skew, jitter zero delay buffers designed distribute high speed clocks. They have (PL123-05) (PL123-09) low-skew output banks, outputs each, that synchronized with input. PL123-09 allows control banks outputs using inputs shown Selector Definition table page synchronization established CLKOUT feed back input PLL. Since skew between input output less than ±100ps, device acts zero delay buffer. input output propagation delay advanced delayed adjusting load CLKOUT pin. These parts intended input-tolerant applications.

LAYOUT RECOMMENDATIONS
following guidelines assist with performance optimized design:
Signal Integrity Termination Considerations
Keep traces short! Trace Inductor. With capacitive load this equals ringing! Long trace Transmission Line. Without proper termination this will cause reflections looks like ringing Design long traces "striplines" "microstrips" with defined impedance. Match trace side avoid reflections bouncing back forth.
Decoupling Power Supply Considerations
Place decoupling capacitors close possible pin(s) limit noise from power supply Addition ferrite bead series with help prevent noise from other board sources Value decoupling capacitor frequency dependant. Typical values 0.1F designs using frequencies 50MHz 0.01F designs using frequencies 50MHz.
Typical CMOS termination Place Series Resistor close possible CMOS output CMOS Output Buffer
