Note 4:

Parameter scales linearly with REFOSC frequency ft.

For any REFOSC frequency other than 4.90MHz, compute new

parameter value as the ratio [(REFOSC FREQ (in MHz) / 4.90] * [Parameter Value @ 4.90MHz]. Example: For REFOSC

Freq. ft = 6.00MHz, [Parameter Value @ 6.00MHz] = (6.00 / 4.90) *[Parameter Value @ 4.90MHz].

Note 5:

Parameter scales inversely with REFOSC frequency ft.

For any REFOSC frequency other than 4.90MHz, compute new

parameter value as the ratio [4.90 / (REFOSC FREQ (in MHz)] * [Parameter Value @ 4.90MHz]. Example: For REFOSC

Freq. ft = 6.00MHz, [Parameter Value @ 6.00MHz] = (4.90 / 6.00) * [Parameter Value @ 4.90MHz].

Note 6:

Demod filter bandwidths are related in a binary manner, so any of the (lower) nominal filter values may be derived simply by

dividing this parameter value by 2, 4, or 8 as desired.
