ZHCSHP9C May 2017 – October 2018 IWR1443
PRODUCTION DATA.
Table 5-1 describes the four rails from an external power supply block of the IWR1443 device.
The 1.3V (1.0V) and 1.8V power supply ripple specifications mentioned in Table 5-2 are defined to meet a target spur level of –105dBc (RF Pin = –15dBm) at the RX. The spur and ripple levels have a dB to dB relationship, for example, a 1dB increase in supply ripple leads to a ~1dB increase in spur level. Values quoted are rms levels for a sinusoidal input applied at the specified frequency.
