Set to 0 for normal operation.
For MAX2393 only:
1 = selects the 3G W-CDMA mode for baseband filters.
0 = selects the TD-SCDMA mode for baseband filters.
Set to 1 for normal operation.
For MAX2390–MAX2393/MAX2401:
0 = disables the RF PLL + LO generation circuit.
For MAX2396/MAX2400:
0 = disables the LO generation circuit.
0 = disables the VCO.
For MAX2390–MAX2393/MAX2401:
A 2-bit word sets the RF charge-pump current as follows:
0 0 = 1000µA
0 1 = 1500µA
1 0 = 2000µA
1 1 = 2500µA
For MAX2396/MAX2400:
Set to 11 for normal operation.
0 = disables on-chip LNA. Set to zero for external LNA.
