S5. SIF S/N [S/N (FM)]
(1) External AGC (V17 = VCC)
(2) fs = 4.5MHz NO MOD Vi = 100mVrms
(3) Measure the output level at test point D. Vn
(4) S/N (FM) = 20log
dB
C2. SIF converter maximum output level [V max]
(1) Internal AGC
(2) fp = 45.75MHz CW; 10mV (VIF input)
fs = 41.25MHz CW; 10mV (1st SIF input)
(3) Measure the 4.5MHz component at test point E (MIX output). V max (dB
V)
Note 1) Unless otherwise specified for VIF test, apply the VCC voltage to the IF AGC and adjust the VCO coil so that
oscillation occurs at 45.75MHz.
2) Unless otherwise specified, the SW1 must be ON.
Sample Application Circuit
* When using a 5V common power supply for VCC1 and VCC2, connect an L (= 10H) across pins 4 to 5,
and disconnect C (100
F and 0.01F) from pin 4.
VO (FM)
