7.5 Power Supply Specifications

Table 7-1 describes the four rails from an external power supply block of the AWR2243 device.

Table 7-1 Power Supply Rails Characteristics
SUPPLYDEVICE BLOCKS POWERED FROM THE SUPPLYRELEVANT IOS IN THE DEVICE
1.8 VSynthesizer and APLL VCOs, crystal oscillator, IF Amplifier stages, ADC, CSI2Input: VIN_18VCO, VIN18CLK, VIN_18BB, VIOIN_18DIFF, VIOIN_18IO
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 DistributionInput: VIN_13RF2, VIN_13RF1
LDO Output: VOUT_PA
3.3 V (or 1.8 V for 1.8 V I/O mode)Digital I/OsInput VIOIN
1.2 VCore Digital and SRAMsInput: 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 1.3V (1.0V) and 1.8V power supply ripple specifications mentioned in Table 7-2 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.
