Description
Oscillator input. Oscillator output. A crystal is placed between OSCIN and OSCOUT. Power supply input for charge pump and analog switch. Power supply voltage input. Charge pump output. The characteristics of charge pump is reversed depending upon FC input. Ground Phase comparator output. Normally this pin outputs high level. While the phase difference of fr, and fp exists, this pin outputs low level. Prescaler input. The connection with an external VCO should be AC connection. Clock input for 19-bit shift register and 16-bit shift register. On rising edge of the clock shifts one bit of data into the shift registers. Binary serial data input. The last bit of the data is a control bit which specified destination of shift registers. When this bit is high level and LE is high level, the data stored in shift register is transferred to 15-bit latch. When this bit is low level and LE is high level, the data is transferred to 18-bit latch. Load enable input (with internal pull up resistor). When LE is high or open, the data stored in shift register is transferred into latch depending upon the control bit. At the time, internal charge pump output to be connected to BISW pin because internal analog switch becomes ON state. Phase select input of phase comparator (with internal pull up resistor). When FC is low level, the characteristics of charge pump, phase comparator is reversed. FC input signal is also used to control fOUT pin (test pin) output level for fr or fp. Analog switch output. Usually BISW pin is set high-impedance state. When internal analog switch is ON (LE pin is high level), this pin outputs internal charge pump state. Monitor pin of phase comparator input. fOUT pin outputs either programmable reference divider output (fr) or programmable divider output (fp) depending upon FC pin input level. Outputs for external charge pump. The characteristics are reversed according to FC input. P pin is N-channel open drain output.

FUNCTIONAL DESCRIPTIONS
SERIAL DATA INPUT
Serial data input is achieved by three inputs, such as Data pin, Clock pin and LE pin. Serial data input controls 15-bit programmable reference divider and 18-bit programmable divider, respectively. Binary serial data is input to Data pin. On rising edge of clock shifts one bit of serial data into the internal shift registers and when load enable pin is high level or open, stored data is transferred into latch depending upon the control bit. Control data "H" data is transferred into 15-bit latch. Control data "L" data is transferred into 18-bit latch.

PHASE CHARACTERISTICS
FC pin is provided to change phase characteristics of phase comparator. Characteristics of internal charge pump output level (Do), phase comparator output level (R, P) are reversed depending upon FC pin input level. Also, monitor pin (fOUT) output level of phase comparator is controlled by FC pin input level. The relation between outputs (DO, R, P) and FC input level are shown below.

NOTES: Phase difference detection range: -2 to +2 Spike appearance depends on charge pump characteristics. Also, the spike is output in order to diminish dead band. When fr > fp or fr < fp, spike might not appear depending upon charge pump characteristics.
ANALOG SWITCH
ON/OFF of analog switch is controlled by LE input signal. When the analog switch is ON, internal charge pump output (DO) to be connected to BlSW pin. When the analog switch is OFF, BlSW pin is set to high-impedance state. LE=H (Changing the divide ratio of internal prescaler) : Analog switch=ON LE=L (Normal operating mode): Analog switch=OFF LPF time constant is decreased in order to insert a analog switch between LPF1 and LPF2 when channel of PLL is changing. Thus, lock up time is decreased, that is, fast lock up time is achieved.
