Read Cycle Start
Unlike daisy chain, the data frames of all the devices in cascade are not seamless and there is a loss of time
between one device 3-state to other device data valid due to wakeup time from 3-state and a two clock phase
shift between SYNC and data (see
Figure 15
for details). As a result, the number of data frames per second in
this mode is less than in daisy chain mode. Also, a maximum of 4 devices can be cascaded on the same bus.
But, I/O power per device is considerably lower in cascade as compared to daisy chain as each device LVDS o/p
goes to 3-state after its data transfer. The deserializer at the output of the last device can shift the data on every
clock falling edge, and it can latch the parallel 16-bit word on the second CLK_O rising edge (shown as 18R)
after every SYNC_O rising edge.
The ADS8413 is a member of the high-speed successive approximation register (SAR) analog-to-digital
converters family. The architecture is based on charge redistribution, which inherently includes a sample/hold
function. The device includes a built-in conversion clock, internal reference, and 200-MHz LVDS serial interface.
The device can be operated at maximum throughput of 2 MSPS.
An analog input is provided to two input pins: +IN and -IN. When a conversion is initiated, the voltage difference
between these pins is sampled on the internal capacitor array. While a conversion is in progress, both inputs are
disconnected from any internal function.
