Note2 Video Band Width : BW
1. Measure the 1MHz component level of Video output (TP24) with a spectrum analyzer when SG3 (f2 =

At that time, measure the voltage at TP21, and then fix TP21 at that voltage.
2. Reduce f2 and measure the value of (f1-f2) when the (f1-f2) component level reaches -3dB from the 1MHz
component level as shown below.

Note6 Capture range : CR-U
1. Increase the frequency of SG7 until the VCO is out of locked-oscillation.
2. And decrease the frequency of SG7 and measure the frequency fU when the VCO is locked.

Note8 Inter modulation : IM
1. Input SG8 to VIF IN(Pin17,18), and measure video output (TP24) with an oscilloscope.
2. Adjust AGC filter voltage TP21 so that the minimum DC level of the output waveform is Vsync.
3. At that time, measure TP24 with a spectrum analyzer. The inter modulation is defined as a difference
between 0.92MHz and 3.58 MHz frequency components.
Note9 RF AGC Delay Point (TV Mode) : RFDP1
1. Input SG12 to VIF IN (Pin17, 18) and gradually reduce level and then measure the input level when RF
AGC output (TP14) reaches 1/2Vcc, as shown below.
2. At that time, the state of Pin3 is DC open.

2. Input SG23 to LIM IN (Pin3), and measure the noise level of AF output (TP7) with FLAT-r.m.s .
3. The input limiting sensitivity is defined as the input level when the difference between each 1kHz

*VCO SW : US/JP
1. Measure the frequency of output signal at AFT out (TP13) each when be selected US or JP by SW5.
2. Measured frequency's are defined FaftUS (US Mode), FaftJP(JP Mode).
The VCO freerun frequency is calculated by following.
<Fref = 3.579545MHz>
US Mode
FvcofUS = 52.915(MHz) - 2×FaftUS(MHz) - 45.75(MHz) [MHz]
JP Mode
FvcofJP = 65.925(MHz) - 2×FaftJP(MHz) - 58.75(MHz)
#
[MHz]
Case of Fref frequency is 4.00MHz, SW11 should be set up 2
(Pin11 is connected 4.7kΩ to GND).
Others condition's are same as case of 3.58MHz mode,and the VCO freerun frequency is calculated by following.
<Fref = 4.00MHz>
US Mode
FvcofUS = 52.952(MHz) - 9×FaftUS(MHz) - 45.75(MHz) [MHz]
JP Mode
FvcofJP = 65.951(MHz) - 9×FaftJP(MHz) - 58.75(MHz)

Recommendation
* By pass capacitance for Logic Vcc (Pin12) should be mounted close hard by Logic GND (Pin10)
* In order to mitigate the surroundings lump by the VIF input, the balanced connection from a SAW filter to the VIF input
pin of 17,18 recommends a putter which serves as a 1t coil by Tip C or the jumper.
