Small Outline Package (SOP)
RF small signal prescaler input. Small signal input from the voltage controlled
oscillator
Power Supply voltage input may range from 2.7V to 5.5V. Bypass capacitors
should be placed as close as possible to this pin and be connected directly
to the ground plane.
Divide Ratio Control. CMOS logic input. Pin functionality is described in the
Modulus Control Truth Table.
Prescaler Output. CMOS level output for connection to low frequency PLL
input.
Ground for analog and digital signals.
Modulus Control Input. High impedance CMOS logic input. Pin functionality is
described in the Modulus Control Truth Table.
Divide Ratio Control. High impedance CMOS logic input. Pin functionality is
described in the Modulus Control Truth Table.
RF small signal prescaler complementary input. In single-ended mode, a
bypass capacitor should be placed as close as possible to this pin and be
connected directly to the ground plane. The IN and IN can be driven
differentially when the bypass capacitor is omitted.
