ADS5277

The ADS527x are high-performance, 40MSPS, 50MSPS, and 65MSPS, 8-channel, parallel analog-to-digital converters (ADCs). 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.

In LVDS, an integrated phase lock loop multiplies the incoming ADC sampling clock by a factor of 6. This high-frequency
LVDS clock is used in the data serialization and transmission process and is converted to an LVDS signal for transmission in parallel with the data. Providing this additional LVDS clock allows for easy delay matching. The word output of each internal ADC is serialized and transmitted either MSB or LSB first. The bit following the rising edge of the ADC clock output is the first bit of the word.

The ADS527x provide internal references, or can optionally be driven with external references. Best performance can be achieved through the internal reference mode.

The ADS527x are available in a PowerPAD TQFP-80 package and are specified over a −40°C to +85°C operating range.
