The PLL[2:0] bits (00h[6:4]) are used to program the
clock multiplier for the internal PLL in order to set the
input sampling frequency range. The default setting
is PLL[2:0] = 001, which allows for 39MHz to 50MHz
operation. See Table 3 for the full range of PLL settings
and the corresponding sampling frequencies.
The NAP_SHDN1 (00h[1]) and NAP_SHDN0 (00h[0]) bits
are used to set the state of the ADC when all channels
are turned off for the SHDN = 1 and SHDN = 0 power-
management states, respectively. When they are set to
logic 0, the device enters sleep mode if no channels are
enabled in that power state. When they are set to logic
1, the device instead enters nap mode if no channels
are enabled for that power state. If even one channel
is active in the current power state, the device cannot
enter nap or sleep mode (Table 4). The default states
are NAP_SHDN1 = 0 and NAP_SHDN0 = 1, meaning
that if all channels are disabled in the corresponding
power state, SHDN = 1 corresponds to sleep mode and
SHDN = 0 corresponds to nap mode.
Output Data Format and Test Pattern Register (01h)
The Output Data Format and Test Pattern register (01h,
Table 5) has several functions. The first is used to adjust
the LVDS output bit order and data format. The second is
used to set the CLKOUT phase with respect to the output
frame. Finally, this register is used to enable and select
test pattern outputs.
