8.5 Power Supply Specifications

Table 8-1 describes the four rails from an external power supply block of the AWR1443 device.

Table 8-1 Power Supply Rails Characteristics
SUPPLY DEVICE BLOCKS POWERED FROM THE SUPPLY RELEVANT IOS IN THE DEVICE
1.8 V Synthesizer and APLL VCOs, crystal oscillator, IF Amplifier stages, ADC, LVDS Input: VIN_18VCO, VIN18CLK, VIN_18BB, VIOIN_18DIFF, VIOIN_18
LDO Output: VOUT_14SYNTH, VOUT_14APLL
1.3 V (or 1 V in internal LDO bypass mode)(1) Power Amplifier, Low Noise Amplifier, Mixers and LO Distribution Input: VIN_13RF2, VIN_13RF1
LDO Output: VOUT_PA
3.3 V (or 1.8 V for 1.8 V I/O mode) Digital I/Os Input VIOIN
1.2 V Core Digital and SRAMs Input: VDDIN, VIN_SRAM
(1) Three simultaneous transmitter operation is supported only in 1-V LDO bypass and PA LDO disable mode. In this mode 1V supply needs to be fed on the VOUT PA pin.

The 1.3-V (1.0 V) and 1.8-V power supply ripple specifications mentioned in are defined to meet a target spur level of –105 dBc (RF Pin = –15 dBm) at the RX. The spur and ripple levels have a dB-to-dB relationship, for example, a 1-dB increase in supply ripple leads to a ~1 dB increase in spur level. Values quoted are rms levels for a sinusoidal input applied at the specified frequency.
