The ADS5271 is a high-performance, 50MSPS, 8-channel analog-to-digital converter (ADC). Internal references
are provided, simplifying system design requirements. Low
power consumption allows for the highest of system
integration densities. Serial LVDS (low-voltage differential
signaling) outputs reduce the number of interface lines and
package size.
An integrated phase lock loop (PLL) multiplies the
incoming ADC sampling clock by a factor of 12. This
high-frequency LVDS clock is used in the data
serialization and transmission process. The word output of
each internal ADC is serialized and transmitted either
MSB or LSB first. In
addition to the eight data outputs, a bit clock and a
word clock are also transmitted. The bit clock is at 6x
the speed of the sampling clock, whereas the word
clock is at the same speed of the sampling clock.
The ADS5271 provides internal references, or can optionally
be driven with external references. Best performance is
achieved through the internal reference mode.
The device is available in a TQFP-80 PowerPAD package and
is specified over a -40°C to +85°C operating range.
