M52342FP
AF S/N
1. Input SG19 (SG24) into SIF input, and measure the output noise level of AF output TP1. This level is named VN.
2. S/N is;
S/N = 20 log VoAF (mVrms) (dB)
VN (mVrms)
CQIF QIF Control
Lower the voltage of V9, and measure the voltage of V9 when DC voltage of TP15 begins to change.
The Note in The System Setup
M52342FP has 2 power supply pins of VCC (pin 16, 17) and Vreg. OUT (pin 20, 21) . VCC is for AFT output, RF AGC
output circuits and 5 V regulated power circuit and Vreg. OUT is for the other circuit blocks.
In case M52342FP is used together with other ICs like VIF operating at more than 5 V, the same supply voltage as that
of connected ICs is applied to VCC and Vreg. OUT is opened. The other circuit blocks, connected to Vreg. OUT are
powered by internal 5 V regulated power supply.
In case the connecting ICs are operated at 5 V, 5 V is supplied to both VCC and Vreg. OUT.
