Figure 12. Phase Detector/Charge Pump Control Register (Write Only)
The Phase Detector/Charge Pump Control Register allows control
of the gain for both phase detectors and configuration of the
LD/PSmain and LD/PSaux signals for frequency power steering or
lock detection. As shown in Figure 12, the values to be loaded
are:
Main Phase Detector Gain = Five-bit value for programmable
main phase detector gain. Range is from 0 to 31 decimal for
31.25 to 1000
A/ 2π radian, respectively.
Main Power Steering Enable = One-bit flag to enable the
frequency power steering circuitry of the main phase detector.
When this bit is cleared, the LD/PSmain pin is configured to be
a lock detect, active low, open collector pin. When this bit is set,
the LD/PSmain pin is configured to be a frequency power
steering pin and can be used to bypass the external main loop
filter to provide faster frequency acquisition.
Auxiliary Phase Detector Gain = Five-bit value for
programmable auxiliary phase detector gain. Range is from 0 to
31 decimal for 31.25 to 1000
A/2π radians, respectively.
Auxiliary Power Steering Enable = One-bit flag to enable the
frequency power steering circuitry of the auxiliary phase
detector. When this bit is cleared, the LD/PSaux pin is
configured to be a lock detect, active low, open collector pin.
When this bit is set, the LD/PSaux pin is configured to be a
frequency power steering pin and may be used to bypass the
external auxiliary loop filter to provide faster frequency
acquisition.
The Power Down/Multiplexer Output Select Control Register
allows control of the power-down modes, internal multiplexer
output, and main
Σ synthesizer fractionality. As shown in
Figure 13, the values to be loaded are:
Full Power Down = One-bit flag to power down the SKY72300-
362 except for the reference oscillator and the serial interface.
When this bit is cleared, the SKY72300-362 is powered up.
When this bit is set, the SKY72300-362 is in full power-down
mode excluding the Mux_out signal (pin 24).
Main Synthesizer Power Down = One-bit flag to power down
the main synthesizer. When this bit is cleared, the main
synthesizer is powered up. When this bit is set, the main
synthesizer is in power-down mode.
Main Synthesizer Mode = One-bit flag to power down the main
synthesizer’s
Σ modulator and fractional unit to operate as an
integer-N synthesizer. When this bit is cleared, the main
synthesizer is in fractional-N mode. When this bit is set, the
main synthesizer is in integer-N mode.
