Description
Multiplexer Output. The multiplexer output allows the lock detect, the N divider value, or the R counter
value to be accessed externally.
Digital Σ-Δ Modulator Power Supply. Place decoupling capacitors to the ground plane as close to this
pin as possible. SDV
Digital Σ-Δ Modulator Ground. All ground pins should be tied together.
Connecting a resistor between this pin and GND sets the charge pump output current. Place the resistor
as close to this pin as possible. The nominal voltage bias at the R
