Description
Ineffective unless CFR2[4] = 1.
0 = enables the SYNC_SMP_ERR pin to indicate (active high) detection of a synchronization
pulse sampling error.
1 = the SYNC_SMP_ERR pin is forced to a static Logic 0 condition (default).
See the Parallel Data Port Modulation Mode section for more details.
See the Parallel Data Port Modulation Mode section for more details. Default is 0000b.
Description
Controls the REFCLK_OUT pin (see Table 7 for details); default is 00b.
Selects the frequency band of the REFCLK PLL VCO (see Table 8 for details); default is 111b.
Selects the charge pump current in the REFCLK PLL (see Table 9 for details); default is 111b.
0 = input divider is selected (default).
1 = input divider is bypassed.
0 = input divider is reset.
1 = input divider operates normally (default).
0 = normal operation (default).
1 = phase detector disabled.
0 = REFCLK PLL bypassed (default).
1 = REFCLK PLL enabled.
This 7-bit number is the divide modulus of the REFCLK PLL feedback divider; default is
0000000b.
Description
This 8-bit number controls the full-scale output current of the main DAC (see the Auxiliary
DAC section); default is 0x7F.
0 = the data assembler of the parallel data port internally forces zeros on the data path
and ignores the signals on the D[15:0] and F[1:0] pins while the TxENABLE pin is Logic 0
(default). This implies that the destination of the data at the parallel data port is
amplitude when TxENABLE is Logic 0.
1 = the data assembler of the parallel data port internally forces the last value received
on the D[15:0] and F[1:0] pins while the TxENABLE pin is Logic 1.
0 = disables parallel data port modulation functionality (default).
1 = enables parallel data port modulation functionality.
