11 REFERENCE Reference frequency input from this pin. The reference frequency

CP INPUT

is 3.58MHz, inserting 270kΩ between this pin to GND.

The reference frequency is 4.0MHz, this pin leaving open.

12 AFT OUTPUT AFT output. AFT center voltage is generated by an external

bleeder. The AFT gain is increased by increasing the resistance

of this external bleeder resister. However, this resister must not

exceed 390Ω.

This circuit includes a control function that control the AFT voltage

to naturally approach the center voltage during weak field

reception.
