When
in is used to output the VC node voltage (0) or to control the VC
node voltage (1).
Power down of the analog test module.
When
is as follows:
0: Outputs “I” (ATEST2) and “Q” (ATEST1) from RxMIX.
1: Inputs “I” (ATEST2) and “Q” (ATEST1) to BPF.
2: Outputs “I” (ATEST2) and “Q” (ATEST1) from VGA.
3: Inputs “I” (ATEST2) and “Q” (ATEST1) to ADC.
4: Outputs “I” (ATEST2) and “Q” (ATEST1) from LPF.
5: Inputs “I” (ATEST2) and “Q” (ATEST1) to TxMIX.
6: Outputs “P” (ATEST2) and “N” (ATEST1) from Prescaler.
7: Connects TX IF to RX IF and simultaneously the ATEST1 pin to the
internal VC node (see
