DATASHEET

Notes:

■

RBIAS is connected to the Analog Ground plane VSSA via a resistor.

■

When the internal 1.8V regulator is enabled, VDD18 (Pin 106) & VDD18PLL (Pin 101), MUST have

a 10uf +/- 20%, (equivalent series resistance (ESR) <0.1ohm) bypass capacitor to VSSA. These

capacitors must be as close to the pins as possible
