DESCRIPTION
PL612-01 advanced dual design based PhaseLink's PicoPLL world's smallest programmable clock, technology. This advanced technology allows output PL612-01 small 3mmx3mm package high performance, low-power, low-cost applications. Besides their small form factor outputs that reduce overall system costs, PL612-01 offers superior phase noise, jitter power consumption performance. power down feature PL612-01, when activated, allows consume less than 10µA power, while Configuration Select (CSEL) function allows switching programmable configurations each PLL, independently. FSELX, other hand, allows frequency switching outputs single clock (CLK2).

LAYOUT RECOMMENDATION
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 inch) "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 Multiple pins should decoupled separately best performance. 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.
