Table 11: VCC_MAIN Supply Power Consumption
Notes
1. The typical current measurements noted in CDMA mode are with the following settings:
a. CDMA-Cellular (800MHz): Band = IS-2000, Cell-Power = -104dBm,
Channel Number 358
b. CDMA-PCS (1900MHz): Band = IS-2000, Cell-Power = -104dBm,
Channel Number 563
Maximum Slot Cycle Index for both 800MHz and 1900MHz modes = 1
2. Measurements are based on worst case scenario—CM52 with 3W option. Values for CM52 with
no 3W option could be marginally lower.
3. A +10% tolerance is allowed for the listed maximum values.
2.4.3.2 VCC_AUX Supply Power Consumption
The VCC_AUX power supply is required for CM52 variants with 3W AMPS circuitry populated. This
requirement is regardless of whether the AMPS Power Class 1 is used.
The VCC_AUX power supply is not required for any CM52 Wireless CPU
®
other than those with 3W
AMPS circuitry populated, but it can be applied if desired. In this case, the VCC_AUX pins can be
supplied as 5V, 13.8V or Grounded.
