ADS6245/ADS6244/ADS6243/ADS6242 (ADS624X) is a family of high performance 14-bit 125/105/80/65 MSPS
dual channel A-D converters. Serial LVDS data outputs reduce the number of interface lines, resulting in a
compact 48-pin QFN package (7 mm
× 7mm) that allows for high system integration density. The device includes
3.5 dB coarse gain option that can be used to improve SFDR performance with little degradation in SNR. In
addition to the coarse gain, fine gain options also exist, programmable in 1dB steps up to 6dB.
The output interface is 2-wire, where each ADC data is serialized and output over two LVDS pairs. This makes it
possible to halve the serial data rate (compared to a 1-wire interface) and restrict it to less than 1Gbps easing
receiver design. The ADS624X also includes the traditional 1-wire interface that can be used at lower sampling
frequencies.
An internal phase lock loop (PLL) multiplies the incoming ADC sampling clock to derive the bit clock. The bit
clock is used to serialize the 14-bit data from each channel. In addition to the serial data streams, the frame and
bit clocks are also transmitted as LVDS outputs.
