Note2 Video Band Width : BW 1. Measure the 1MHz component level of Video output (TP24) with a spectrum analyzer when SG3 (f2 = 44.75MHz) is input to VIF IN (Pin17, 18). 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.

(f1-f2) 1MHz BW
Note3 Input Sensitivity : VinMIN Input SG4 (Vi = 90dB) to VIF IN(Pin17, 18), and then gradually reduce Vi and measure the input level when the 20kHz component of Video output (TP24) reaches -3dB from Vo det level. Note4 Maximum Allowable Input : VinMAX 1. Input SG5 (Vi = 90dB) to VIF IN (Pin17, 18) , and measure the level of the 20kHz component of Video output (TP24). 2. Gradually increase the Vi of SG5 and measure the input level when the output reaches -3dB. Note5 AGC Control Range : GR
GR = VinMAX - VinMIN (dB)
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.
CR-U = fU -45.75 (MHz)
Note7 Capture range : CR-L 1. Decrease the frequency of SG7 until the VCO is out of locked-oscillation. 2. And increase the frequency of SG7 and measure the frequency fL when the VCO is locked.
CR-L = 45.75 - fL (MHz)

M61112FP 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.

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. US Mode FvcofUS = 52.915(MHz) - 2xFaftUS(MHz) - 45.75(MHz) [MHz] JP Mode FvcofJP = 65.925(MHz) - 2xFaftJP(MHz) - 58.75(MHz) # [MHz]
Case of Fref frequency is 4.00MHz, SW11 should be set up 2 (Pin11 is connected 4.7k to GND). Others condition's are same as case of 3.58MHz mode,and the VCO freerun frequency is calculated by following. US Mode FvcofUS = 52.952(MHz) - 9xFaftUS(MHz) - 45.75(MHz) [MHz] JP Mode FvcofJP = 65.951(MHz) - 9xFaftJP(MHz) - 58.75(MHz) [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.
