to 10V
PNP open collector method is used. When the band switching data is "H", the output is ON. When it is "L", the output is OFF.
DC-DC power supply voltage terminal. 5.0V ± 0.5V When potential difference with VDC terminal becomes more than 0.33V by current
limiting detector of DC-DC converter, the listing rises with off.
Power supply voltage for turning voltage.
This is the output terminal for the LPF input and charge pump output. When the phase of the programmable divider output (f 1/N) is ahead compared to the reference
frequency (f
), the "source" current state becomes active.
REF
If it is behind, the "sink" current becomes active. If the phases are the same, the high impedance state becomes active. Lock detector output. When loop of phase locked loop locked it, it rises with "H" level
in "L" level or unlock. In control byte data input, the programmabule freq. divider output and reference freq.
output is selected by the test mode. Set up reference frequency divider ratio. In "L" level, set it up in 1/640(19Bit) in setting "opening" in 1/1024(19Bit) or 1/512
(18Bit).
This is normally at a "L". When this is at "H", data and cloc k signals are receiv ed. Data is read into the latch when the enable signal after the 18th signal of the clock signal falls or when the 19th pulse of the clock signal falls.
4.0MHz crystal oscillator is connected.
