The ODT-AFE-1T1R-12 is an ultra-high-performance Swift™ AFE designed in a 12nm CMOS process. The AFE includes one 12-bit, 2GSPS I/Q ADC pairs, one 12-bit, 1.6GSPS I/Q DAC pairs, 2 capless LDOs, a voltage / current reference, and a low jitter PLL. The ADC and DAC architecture is optimized to maximize performance while minimizing power and area consumption. To maximize SNR, the AFE includes an ultra-low-jitter clock distribution network.
