Ideal for point-to-point microwave links and digital oscilloscopes, the 2/1 channel 8-bit, 450/900 Msamples/s HMCAD1512 ADC utilizes time-interleaving to achieve the higher sampling rate. The device contains two ADCs that can be interleaved by the user to act as a single channel or two channels. In dual channel mode, either of the two inputs can be selected for each ADC channel for maximum sample rate at 450 MSPS. In single channel mode, either of the two inputs can be selected as a valid input to the single ADC channel for maximum sample rate at 900 Msamples/s.
At full speed operation, the ADC offers a total power consumption of only 650 mW including I/O ) and delivers an SNR of 49 dBFS when applied with an input signal of 170 MHz. The internal resolution in the HMCAD1512 core is 13-bit providing a digital gain of 1X to 50X. Subsequently, the full scale range of operation can be varied from 2 Vp-p down to 63 mVp-p.
