DESCRIPTION
The ADS5270 is a high-performance, 40MSPS, 8-channel,
parallel 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 multiplies the incoming ADC
sampling clock by a factor of 12. This 12x clock is used in the
process of serializing the data output from each channel. The
12x clock is also used to generate a 1x and a 6x clock, both
of which are transmitted as LVDS clock outputs. The 6x clock
is denoted by the differential pair LCLKP and LCLKN, while the
1x clock is denoted by ADCLKP and ADCLKN. The word
output of each ADC channel can be transmitted either as MSB
or LSB first. The bit coinciding with the rising edge of the 1x
clock output is the first bit of the word. Data is to be latched by
the receiver on both the rising and falling edges of the 6x clock.
The ADS5270 provides internal references, or can optionally
be driven with external references. Best performance can be
achieved through the internal reference mode.
The device is available in a PowerPAD TQFP-80 package and
is specified over a 40
°
C to +85
°
C operating range.
