Preliminary specification
Double mixer/oscillator for TV and VCR
tuners
TDA5332T
Notes to the characteristics
1.
The values have been corrected for hybrid and cable losses. The symmetrical output impedance of
the circuit is 100
.
2.
The input level of a N

1 MHz signal (just visible).
3.
The gain is defined as the transducer gain (measured in Fig.3) plus the voltage transformation ratio
of L6 to L7 (6:1, 16 dB).
4.
All S parameters are referred to a 50
system.
5.
The input power is defined as the power delivered by the generator on a 50
load.
6.
The frequency shift is defined for a variation of power supply from;
a) V
P
= 12 V to V
P
= 10.8 V
b) V
P
= 12 V to V
P
= 13.2 V.
In both cases the frequency shift is below the specified value.
7.
The frequency drift is defined for a variation of ambient temperature from;
a) T

C to T
amb
= 0

b) T
amb
= 25
