Comments
Default SPI configuration is
3-wire, MSB first.
PWR_DWN = 0.
Default setting is for all
blocks powered on.
PWR_DWN = 1.
Default setting* is for all
functional blocks powered
down except PLL.
*MODE = CONFIG = 1.
Setting has PLL powered
down with OSCIN input
routed to RXCLK output.
Default setting is for TXEN
input to control power
on/off of Tx/Rx path.
Tx driver delayed by 31
1/f
Default setting is Duty Cycle
Restore disabled, ADC CLK
from OSCIN input, and PLL
multiplier × 2 setting.
*PLL multiplier × 4 setting.
Full-duplex RXCLK normally
at nibble rate.
*Exception on power-up.
Default setting is CLKOUT2
and CLKOUT1 enabled with
divide-by-2.
*CLKOUT1 and CLKOUT2
disabled.
Default setting has LPF ON
and Rx path at nominal
power bias setting.
*Rx path to low power.
