Technical Information
Explanation of each block
1. VIF
1) Adapting the inter carrier PLL coherent detection method.
2) The VCO of VIF is controlled by I
2
C bus (7-bit): Oscillation at 1/2 of the f
P
frequency. (2 times multiplier
circuit is inside.) Built-in double APC circuit of frequency and phase.
3) AFT without coil: It is applicable to both VS and FS tuners by amplifying the error voltage of APC and
making S-curve to obtain AFT output. The DC offset is controlled by I
2
C bus (9-bit). The AFT defeat is also
possible.
4) Since the VCO oscillates at 1/2 frequency, a high-frequency disturbance such as tweet is reduced.
5) The video detection output is 2.0 V[p-p] typical: The level adjustment is carried out by I
2
C bus .
6) The built-in lock detection circuit realizes a stable pulling by the changeover of time constant for APC.
7) The delay point of RF AGC is adjusted by I
2
C bus (6-bit).
2. SIF
1) The SIF detection uses PLL coherent detection method.
2) 4 frequencies are changed over for use as the VCO oscillation frequency.
At NTSC; 4.5 MHz
At PAL; 5.0 MHz, 5.5 MHz, 6.5 MHz
3) It is possible for the SIF detection output to deal with the difference in deviation of PAL/NTSC by changing
over an amplifier of
+
6 dB.
4) Built-in video/SIF SW.
Video SW; 2 systems (with 6 dB amp.)
SIFSW; 3 systems
