The SD1148 is a dual-channel, 14-bit, analog-to-digital converter (ADC) supporting sampling rates up to 210MSps. The device uses a multistage pipeline architecture to achieve high signal-to-noise ratio (SNR) and linearity, over wide input signal bandwidth. The SD1148 can be set to operate using either CMOS or LVDS output interface. Programming for configuration and control is accomplished using a 3-wire SPI-compatible serial bus. The digital output data can be programmed to be delivered in offset binary, twos complement format, or gray code.
The device includes a DSP block that features decimation, digital down conversion (DDC), and IQ mismatch correction.
