Analog Front End: 4 channels of 12-bit 2 GSPS ADC IQ Pairs, 4 channels of 12-bit 2 GSPS DAC IQ Pairs, PVT & Integrated PLL

The ODT-AFE-4T4R-12 is an ultra-high-performance AFE designed in a 12nm process. The AFE includes 2 IQ Pairs of Tx and Rx for the FR2 band, and combines them with 2 additional IQ Pairs of Tx and Rx for the FR1 band clocked at a lower sample rate. This is comprised of eight 12-bit 2GSPS ADCs, and 8 12-bit 2GSPS DACs for 4 total IQ pairs for Tx and Rx. This AFE also includes multiple capless LDOs, a voltage/current reference, and a low jitter 2 GHz 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.
