DATASHEET
Notes:
RBIAS is connected to the Analog Ground plane VSS via a resistor.
When the internal 1.8V regulators are enabled, VDD18 (Pin 86) & VDD18PLL (Pin 124), MUST
have a 10uf +/- 20%, (equivalent series resistance (ESR) <0.1ohm) bypass capacitor to VSS.
These capacitors must be as close to the pins as possible.
