See the ODS_RATEL for description of the serializer data rates.
Sets Warm-Up Time for DIVIDER.
Sets the "warm up" interval for the DIVIDER, where it is biased up prior to transmis-
sion or on the transition from OOK Zero bit to OOK One bit. Set this value in a way
that the warm-up interval of the divider should be 5us for a given ODS clock rate.
Interval is in 4 x clk_ods cycles resolution
Interval = 4 x ods_warm_div x (ods_ck_div+1)/24 MHz
Using the Si4010 calculator spreadsheet in order to determine the correct value of
this parameter is strongly recommended.
Sets Warm-Up Time for PA.
Sets the "warm up" interval for the PA, where it is biased up prior to transmission or
on the transition from OOK Zero bit to OOK One bit. Set this value in a way that the
warm-up interval of the PA should be 1us for a given ODS clock rate. Interval is
directly in clk_ods cycles. Interval = ods_warm_pa x (ods_ck_div+1)/24 MHz
Using the Si4010 calculator spreadsheet in order to determine the correct value of
this parameter is strongly recommended.
