Modulator Divider

01100000 96 38 kHz

Value (MD).

00000110 6 R 527kHz

MD=(3.6864E6/FR)-

1, where MD =

divider value and

FR = desired

modulation

frequency.

The transmitted modulation frequency will be exact. The receive carrier detection frequency can be

slightly different from the programmed frequency (see Receive ASK Carrier Timing Register).
