Operating Characteristics
For the following conditions unless otherwise specified:
MCLK Frequency = 9.216MHz, Symbol Rate = 18k bits/sec,
(VDD - VSS) = (VCC1 - VSS1) = (VCC2 - VSS2) = (VCC3 - VSSB) = (VDD1 - VSSA) = 3.0V to 3.6V for 3.3V
parameters, 4.5V to 5.5V, for 5.0V parameters. Tamb = - 40°C to +85°C.
At 5V, Bias/Ctrl = 0 and at 3.3V Bias/Ctrl = 1 in PowerDownCtrl register will optimise the analogue
performance in the Tx and Rx sections.
It is assumed that all powersave and clock stop bits are set, where appropriate.
