■PIN DESCRIPTIONS

Pin no.		Pin	I/O	Descriptions
SSOP	BCC	name
1	16	OSCIN	I	Programmable reference divider input. Connection to a TCXO.
2	1	OSCOUT	O	Oscillator output.
3	2	VP	–	Power supply voltage input for the charge pump.
4	3	VCC	–	Power supply voltage input.
5	4	DO	O	Charge pump output.
				Phase of the charge pump can be selected via programming of the FC bit.
6	5	GND	–	Ground.
7	6	Xfin	I	Prescaler complementary input, which should be grounded via a capacitor.
8	7	fin	I	Prescaler input.
				Connection to an external VCO should be done via AC coupling.
				Clock input for the 19-bit shift register.
9	8	Clock	I	Data is shifted into the shift register on the rising edge of the clock.
				(Open is prohibited.)
10	9	Data	I	Serial data input using binary code.
				The last bit of the data is a control bit. (Open is prohibited.)
				Load enable signal input. (Open is prohibited.)
11	10	LE	I	When LE is set high, the data in the shift register is transferred to a latch
				according to the control bit in the serial data.
				Power saving mode control. This pin must be set at “L” at Power-ON.
12	11	PS	I	(Open is prohibited.)
				PS = “H”; Normal mode
				PS = “L”; Power saving mode
				Forced high-impedance control for the charge pump (with internal pull up
13	12	ZC	I	resistor.)
				ZC = “H”; Normal Do output.
				ZC = “L”; Do becomes high impedance.
				Lock detect signal output (LD)/phase comparator monitoring output (fout).
14	13	LD/fout	O	The output signal is selected via programming of the LDS bit.
				LDS = “H”; outputs fout (fr/fp monitoring output)
				LDS = “L”; outputs LD (“H” at locking, “L” at unlocking.)
15	14	φP	O	Phase comparator N-channel open drain output for an external charge
				pump. Phase can be selected via programming of the FC bit.
16	15	φR	O	Phase comparator CMOS output for an external charge pump. Phase can
				be selected via programming of the FC bit.
