XWR1xx is a family of Texas Instrument’s mmWave Radar sensor devices with RFCMOS technology. These devices are intended for the automotive and industrial applications. The devices are powered by four voltage rails, namely 3.3 V, 1.2 V, 1.8 V and 1.0 V.

Contents of this document apply to the following mmWave devices:

• xWR1xxx/xWR2xxx
• xWR6xxx

Out of the four Power supply rails mentioned above, the 1.0 V and the 1.8 V supplies are sensitive to the supply ripple and noise because these supplies feed the critical blocks in the device like PLL, baseband ADC, synthesizer, and so forth. For more details on the power supply rail and the logic that it feeds in the device, see the device-specific data sheet. Table 2-1 and Table 2-2 provide the ripple and noise spec for 1.0 V

Table 2-3 and Table 2-4 provide the ripple and noise spec for 1.8 V.
