Description
Qualifying Clock for the TRXD Bus.
Qualifying Clock for the TXD Bus. It can be configured as either an input or output.
Dual Function Pin. In half-duplex mode (TXnRX), this pin controls the direction of the TRX port. In full-
duplex mode (TXIQ), this input signal indicates to which DAC, I or Q, the TxDAC input data is intended.
TxDAC Input Data.
Digital Core 1.8 V Supply.
Output of DLL18V Voltage Regulator.
DLL Filter Output.
Output of CLK18V Voltage Regulator.
Differential Input Clock.
Input to CLK18V and DLL18V Voltage Regulators (1.8 V to 3.3 V). If LDOs are not being used, short Pin 58
to Pin 55. CLK33V must track TXVDD.
Complementary DAC Q Current Outputs.
Analog Supply Voltage for Tx Path (1.8 V to 3.3 V). TXVDD must track CLK33V.
Common-Mode Input Voltage for the I and Q Tx DACs.
Decoupling Point for Internal DAC 1.0 V Bandgap Reference. Use a 0.1 µF capacitor to AGND.
Transmit Path Ground.
Complementary DAC I Current Outputs.
Auxiliary DAC B Output.
Auxiliary DAC A Output.
Selectable Analog Pin. Programmable to either Input 3 of the auxiliary ADC or to the auxiliary DAC10B
output.
Selectable Analog Pin. Programmable to either Input 2 of the auxiliary ADC or to the auxiliary DAC10A
output.
Input 1 of Auxiliary ADC.
Thermal Pad Under Chip. This must be connected to AGND for proper chip operation. It provides both a
thermal and electrical connection to the PCB.
