OSC
IN
I
The programmable reference divider input. TCX0 should be connected with a AC
coupling capacitor.
2
20
GND
Ground for OSC input buffer and the shift register circuit.
3
1
fin
TX
I
Prescaler input pin for the TX-PLL.
Connection to an external VCO should be via AC coupling.
4
2
Xfin
TX
I
Prescaler complimentary input pin for the TX-PLL section.
This pin should be grounded via a capacitor.
5
3
GND
TX
Ground for the TX-PLL section.
6

V
CCTX
Power supply voltage input pin for the TX-PLL section(except for the charge pump
circuit), the oscillator input buffer and the shift register.
7
5
PS
TX
I
Power saving mode control for the TX-PLL section. This pin must be set at “L”
Power-ON. (Open is prohibited.)
PS
TX
= “H” ; Normal mode / PS
TX
= “L” ; Power saving mode

Vp
TX
Power supply voltage input pin for the TX-PLL charge pump.

7
D
OTX
O
Charge pump output for the TX-PLL section.
10
8
LD/fout
O
Lock detect signal output (LD)/phase comparator monitoring
output (fout).The output signal is selected by LDS bit in the serial data.
LDS bit = “H” ; outputs fout signal / LDS bit = “L” ; outputs LD signal

17
15
fin
RX
I
Prescaler input pin for the RX-PLL.
Connection to an external VCO should be via AC coupling.
18
16
LE
I
Load enable signal input(with the schmitt trigger circuit).
When LE is set “H”, data in the shift register is transferred to the
corresponding latch according to the control bit in a serial data.
19
17
Data
I
Serial data input(with the schmitt trigger circuit).
A data is transferred to the corresponding latch(TX-ref. counter, TX-prog. counter,
RX-ref.counter, RX-prog.counter) according to the control bit in a serial data.
20
18
Clock
I
Clock input for the 23-bit shift register (with a schmitt trigger circuit).
One bit of data is shifted into the shift register on a rising edge of the clock.
