19-3144; Rev 1; 3/04 Quad, 12-Bit, 65Msps, 1.8V ADC with Serial LVDS Outputs General Description The MAX1127 quad, 12-bit analog-to-digital converter (ADC) features fully differential inputs, a pipelined architecture, and digital error correction. This ADC is optimized for low-power, high-dynamic performance for medical imaging, communications, and instrumentation applications. The MAX1127 operates from a 1.7V to 1.9V single supply and consumes only 563mW while delivering a 69.6dB signal-to-noise ratio (SNR) at a 19.3MHz input frequency. In addition to low operating power, the MAX1127 features a 675µA power-down mode for idle periods. An internal 1.24V precision bandgap reference sets the ADC’s full-scale range. A flexible reference structure allows the use of an external reference for applications requiring increased accuracy or a different input voltage range. A single-ended clock controls the conversion process. An internal duty-cycle equalizer allows for wide variations in input-clock duty cycle. An on-chip phaselocked loop (PLL) generates the high-speed serial low-voltage differential signaling (LVDS) clock. The MAX1127 provides serial LVDS outputs for data, clock, and frame alignment signals. The output data is presented in two’s complement or binary format. Refer to the MAX1126 data sheet for a pin-compatible 40Msps version of the MAX1127. The MAX1127 is available in a small, 10mm x 10mm x 0.9mm, 68-pin QFN package with exposed paddle and is specified for the extended industrial (-40°C to +85°C) temperature range.
