Dual 12-bit pipeline at 65 MSPS — what the sampling rate buys you
The ADC12DL065CIVS/NOPB is a Texas Instruments dual 12-bit pipelined ADC that digitizes two differential input channels simultaneously at 65 MSPS each. That sampling rate means it can capture a 32.5 MHz input signal at Nyquist without aliasing — enough for IF-sampling in communications receivers, radar I/Q channels, or high-speed data acquisition where both channels must share the same time base.
Supply rails and reference — separating analog from digital
The separate rails let the designer isolate the noisy digital I/O ring from the sensitive analog core — a common layout practice is to feed the analog rail from a low-noise LDO and the digital rail from the system's 3.3 V bus.
Parallel interface — GPIO budget check
Data comes out on a parallel bus — 12 bits per channel, plus an output clock and a frame-sync signal. The host FPGA or DSP needs enough dedicated GPIOs to catch all 12 bits every 15.4 ns cycle. A serial-interface ADC would save pins, but the parallel bus gives deterministic latency with no serialization delay, which matters when the two channels must be correlated in time.
