TERMINAL FUNCTIONS
PIN No. PIN NAME FUNCTION INTERFACE CIRCUIT
1
NF Compares the phase of the input RF signal against the frequency data and feeds back its difference output from the current pump.
16
Charge pump output
2
X'tal OSCin
Crystal oscillator pins to generate the reference signal for the phase comparator. Consist of the inverter amp.
3
X'tal OSCout
4
SDA
Normally used as input / output pins 2 for the I C bus serial data. In TEST mode, used as the input pin for the signal to be compared by the phase comparator.
5
SCL
Normally used as the I C bus serial clock input. In TEST mode, used to input the reference signal of the phase comparator.

P4
Output can be controlled by setting the band switch data. The circuit configuration is open collector output. Each pin has a built-in comparator. The status of the comparator can be checked in READ mode. In TEST mode, P7 is a counter output which allows counter operation to be checked.

TD7626F,TD7626FN
PIN No. PIN NAME FUNCTION Output can be controlled by setting the band switch data. The circuit configuration is open collector output. An A / D converter is built in. In READ mode, five levels of applied voltage can be read. In TEST mode, outputs the reference signal derived by dividing the crystal OSC signal by the set divider ratio. This allows operation to be checked. INTERFACE CIRCUIT

P6
10
P3
Basically used as the address setting pin. The sub-address can be changed by applied voltage. Can be used as a band switch as well, but incorporates resistance (12k) for limiting current.
11
P0
Output can be controlled by setting the band switch data. Incorporates resistance (12k) for limiting current. (Can also be used for setting the prescaler in TEST mode.) (Open collector output)
