FEATURES

• Advanced Programmable PLL design for low-

frequency (KHz) input applications.

• OTP selectable AC/DC Ref. Coupling.

• Accepts <1.0V reference signal input voltage

• Very low Jitter and Phase Noise (30-70ps Pk-Pk typical)

• Output frequency up to

o 133MHz @ 1.8V operation

o 166MHz @ 2.5V operation

o 200MHz @ 3.3V operation

o 6-pin DFN (2.0mmx1.3mmx0.6mm)

o 6-pin SC70 (2.3mmx2.25mmx1.0mm)

o 6-pin SOT23 (3.0mmx3.0mmx1.35mm)

• Input Frequency: 10KHz – 200MHz

• Single 1.8V, 2.5V, or 3.3V ± 10% power supply

• Operating temperature range from 0°C to 70°C

DESCRIPTION

The PL611s-15 is a low-cost general purpose

frequency synthesizer and a member of PhaseLink’s

(QTC)’ family. Designed to fit in a small SOT23,

SC70, or DFN package for high performance

applications, the PL611s-15 accepts low frequency

(>10KHz) Reference input and generates up to

200MHz output with the best phase noise, jitter

performance, and power consumption for handheld

devices and notebook applications. Cascading

PL611s-15 with other PicoPLL ICs could result in

producing all required system clocks with specific

savings in board space, power consumption, and

cost.
