DESCRIPTION
The ADS5240 is a high-performance, 4-channel,
40MSPS 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.

SBAS326C–JUNE 2004–REVISED DECEMBER 2004
4-Channel, 12-Bit, 40MSPS ADC
with Serial LVDS Interface
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 LCLK
and LCLK
,
while the 1x clock is denoted by ADCLK
and
ADCLK
. 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 ADS5240 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 an HTQFP-64 PowerPAD
package and is specified over a -40
°
C to +85
°
C
operating range.
