DEVICE CONFIGURATION
PARALLEL CONFIGURATION ONLY
SLAS631A – APRIL 2009 – REVISED JULY 2009 ............................................................................................................................................................. www.ti.com
Figure 5. CMOS Interface Timing
ADS62C17 can be configured independently using either parallel interface control or serial interface
programming.
To put the device in parallel configuration mode, keep RESET tied to high (AVDD).
Now, pins SEN, SCLK, CTRL1, CTRL2 and CTRL3 can be used to directly control certain modes of the ADC.
The device can be easily configured by connecting the parallel pins to the correct voltage levels (as described in
Table 3 to Table 6. There is no need to apply reset and SDATA can be kept low.
In this mode, SEN and SCLK function as parallel interface control pins. Frequently used functions can be
controlled in this mode – Power down modes, internal/external reference, selection between LVDS/CMOS
interface and output data format.
Table 4 has a brief description of the modes controlled by the four parallel pins.
