... U2730B-B Reference Divider Four different scaling factors of the reference divider can be selected by the input Pin S: 32, 35, 36, 48. Starting from a reference oscillator frequency of 16.384 MHz/ 17.92 MHz/ 18.432 MHz/ 24.576 MHz these scaling factors result in an output frequency of the reference divider of 512 kHz. If the input control Pin C is left open ...
