|1||OSCIN||Crystal oscillator connection pin serving as a reference divider input pin (Oscillator circuit input pin)|
|2||OSCOUT||Crystal oscillator connection pin (Oscillator circuit output pin)|
|3||VP||Power supply pin for charge pump output. Connect this pin to VCC when the internal charge pump is not used.|
|4||VCC||Power supply pin|
|5||DO||Internal charge pump output pin|
|7||LD||Lock detector output pin. When locked: LD = H, When unlocked: LD = L|
|8||fIN||Prescaler input pin. The pin must be AC-coupled for input.|
|9||Clock||Clock input pin for 19-bit and 16-bit shift registers. The shift resistors reads data at the rise of the clock pulse.|
|10||Data||Binary-coded serial data input pin. The last bit in the data is a control bit.|
Control bit = H: Sends data to the 15-bit latch.
Control bit = L: Sends data to the 18-bit latch.
|11||LE||Load enable signal input pin (with pull-up resistor). When LE = H, the pin sends the contents of the shift register to the latch according to the control bit.|
|12||FC||Phase comparator phase switching pin (with pull-up resistor). When FC = L, the pin inverts characteristics of the phase comparator.
It also switches the fout pin (test pin) output between fr and fp.|
|13||fr||Monitor pin of phase comparator input. It is the same as the programmable reference divider output.|
|14||fp||Monitor pin of phase comparator input. It is the same as the programmable divider output.|
|15||øP||Phase comparator output pin for external charge pump. This pin is an N channel open-drain output.|
|16||øR||Phase comparator output pin for external charge pump. This pin is a CMOS output.|
