TA1395FNG Datasheet, PDF (11/24 Pages) Toshiba Semiconductor – Mixer/Oscillator and PLL IC for TV/VCR Tuner

Test Conditions
Conversion Gain (see 1)
RF Input level = -40dBmW (untuned)
TA1395FNG
IF Output Power Level (see 2)
Measure IF output level when it is maximum level.
Conversion Gain Shift (see 3)
The conversion gain shift is defined as a change in conversion gain when supply voltage varies from Vcc = 5 V to 4.5 V or
from Vcc = 5 V to 5.5 V.
Noise Figure (see 4)
Noise figure meter used. Direct reading. (DSB)
Frequency Shift (the PLL is not operating) (see 5)
The frequency shift is defined as a change in oscillator frequency when supply voltage varies from Vcc = 5 V to 4.5 V or
from Vcc = 5 V to 5.5 V.
Switch On Drift (the PLL is not operating) (see 6)
It is frequency change of oscillator by three minutes on the basis of the three seconds back of an after a power supply.
1% Cross Modulation (see 7)
z fd = fp : (fd input level = -40dBmW)
z fud = fp ʶ12MHz, 100 kHz AM30%

Input two signals, and increase the fud input level.
Measure the fud input level when the suppression level reaches 56.5dB.
C/S Beat (see 8)
z fp
z fs = fp + 4.5MHz
z fc = fp + 3.58MHz
fp = fs = fc : 3 signal are same level input
Measure the suppression level when the PIF(45.75MHz) level is -10dBmW output.
Ch Beat (see 9)
*Ch5 beat
z fp = 77.25MHz
z fud = 83.25MHz
Lo = 123MHz tuning
Beat frequency = fud ʷ 2 – Lo = 43.5MHz
fp = fud : 2 signal are same level input
Measure the suppression level when the PIF(45.75MHz) level is -10dBmW output.
*Ch6 beat
z fp = 83.25MHz
z fs = 87.75MHz
Lo = 129MHz tuning
Beat frequency = fp + fs – Lo = 42MHz
fp = fs : 2 signal are same level input
Measure the suppression level when the PIF(45.75MHz) level is -10dBmW output.
*ChA-5 beat
z fp = 91.25MHz
Lo = 137MHz tuning
Beat frequency = Lo – fp ʷ 2 = 45.5MHz
Measure the suppression level when the PIF(45.75MHz) level is -10dBmW output.
