ADS5240

SBAS326C – JUNE 2004 – REVISED DECEMBER 2004

4-Channel, 12-Bit, 40MSPS ADC

with Serial LVDS Interface

FEATURES

•

Maximum Sample Rate: 40MSPS

12-Bit Resolution

No Missing Codes

Power Dissipation: 607mW

CMOS Technology

Simultaneous Sample-and-Hold

70.5dBFS SNR at 10MHz IF

Internal and External References

3.3V Digital/Analog Supply

Serialized LVDS Outputs

Integrated Frame and Bit Patterns

MSB and LSB First Modes

Option to Double LVDS Clock Output Currents

Pin- and Format-Compatible Family

HTQFP-64 PowerPAD™ Package

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.

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.
