UAA2062
FUNCTIONAL DESCRIPTION
Power supply and power management
POWER SUPPLY VOLTAGE
The UAA2062 is used in a cordless telephone handset and
in a base unit. The handset unit is battery powered and can
operate on three NiCad cells. The minimum supply voltage
(VCC) is 3.0 V. However the low-battery detector, crystal
oscillator, clock divider and internal voltage regulator will
function with a supply voltage of 2.85 V.
POWER SAVING OPERATION MODES
When the UAA2062 is used in a handset, it is important to
reduce the current consumption. There are 3 power saving
modes in addition to the active mode:
1. In the active mode all blocks are powered.
2. In the RX mode, all circuitry in the receiver part is
powered.
3. In the standby mode, all circuitry is powered down
except the crystal oscillator, the microcontroller
interface and the Vref(PLL) block.
4. In the inactive mode, all circuitry is powered down
except the microcontroller interface and the Vref(PLL)
block.
Latch memory is maintained in all modes. Table 1 shows
which blocks are powered in each mode.

Note
1. In the standby mode and in the inactive mode, by default, Vref(PLL) remains regulated but is not calibrated
(bit VREFPLL disable is logic 0). If bit VREFPLL disable is logic 1, Vref(PLL) is not regulated and fluctuates with VCC.
MAXIMUM CURRENT CONSUMPTION
Table 2 shows the typical and the maximum current consumption in the active mode and the three current saving modes
under the following conditions: IP3 HIGH mode (bit IP3 is logic 1), see Table 6; LNA gain is step 3 (bits LNA are logic 11),
see Table 12 and the PA output level is step 3 (bits PA are logic 11), see Table 15.
In the standby mode and in the inactive mode, pin Vref(PLL) is not powered (bit VREFPLL disable is logic 1) and the clock
output signal is disabled (bits clock divider ratio are logic 00).
