(Active-Low) 3 Signal bandwidth at pin 6 « For AM, the bandwidth depends on the OF (BFUH50CN) at pin 11. If a capacitor is connected in place of the CF, the bandwidth will get wider. . For FM, the bandwidth depends on the LED Lighting Bandwidth - Kitz & resistance across pins 9 and 22. If the NWN resistance is increased, the bandwidth will get narrower. R=15kohn makes the — bandwidth approximately 120kHz. Resistance across Fins 9 and 22 - koh 4 Sensitivity adjustment of LED, miting, stop signal » For FM, the semifixed variable resistor across pin 15 and GND is used. : For AM, the semifixed variable resistor across pins 15 and 16 is used. Be sure to start adjustment for FM, and then make adjustment for AM. For the stop signal sensitivity and FM'stop signal bandwidth, the variations should be considered and it is reconnended to use the senifixed variable resistor for adjustment. 5 LED lighting sensitivity setting for AM For the LED lighting sensitivity setting for AM, it is desirable that the IC input be 30dBu (antonna input: approximately 504B/m). In this case, the value of WR1 is 30kohms. eirisatacessbiglnsbintas neltva 6 LED lighting sensitivity setting for FM er For the LED lighting sensitivity setting hes, pooslaethy for FM, the IC input may be 45dbu to 60dBu. "With the variations in the front end considered, it is ideal that the IC input in a standard receiving set be 51dBu to 54dBu. The lower value of VR2 for the LED lighting sensitivity setting is as illustrated right. Since the va~ riations in the front end cause the IC input setting sensitivity to vary, it is recommended to use a value of VR2 at an input voltage lower than a standard set~ 7 ting by 643 or greater. For example, if 10 mut apa IC input 53dBu ds taken as a standard, use VR2=100kohms at IC input 474Bu. 2. AM/FM changeover 1 Two selections are available for changeover as shown below: (A) pin 19-used nethod and (B) pin 20-used method. 2 For (A), the voltage on pin 19 relative to Voc (pin 7) must be within the range of -0.8V to +0.1V. If not within {his range, distortion and selectivity will get worse. 3 For (A), a resistance of 68kohms at the IFT cold terminal, which 4s used to prevent the changeover eirouit fron malfunctioning, must be connected.

Local OSC buffer output 1 Local OSC buffer output waveforn is saw-toothed at the SW mode, connect a resistance of 1.2kohms or thereabouts across pin 24 and GND. 4, AM dnput pin 1 It is desirable that the AM input pin (pin 21) be L-coupled to pin 20, 2 Inputting to pin 21 can be done by DC-cutting with a capacitor. However, an unbalance in the RF amplifier (differential amplifier) causes gain drop’ and whistle worsening. 5. Capacitance across pin 9 and GND ¥9 - Modulation Frequency ‘A large capacitance across pin 9 and GND Veceasbv may cause a misstop at an adjacent channel ior rest0.av when the channel select speed is made dev. 2754h2 faster at the automatic channel select 9 ' mode. In this case, decrease the £ capacitance across pin 9 and GND. However, @ c e Sd if too decreased, the LED will flutter at low modulation frequencies at the time of detuning, Therefore, it is recommended to fix the capacitance across pin 9 and GND to be 3.3uF to 10uP. The relation between modulation frequency and demodulation output voltage on pin 9 with the ‘00 capacitance across pin 9 and GND as a Modulation Freavency - ix Parameter is shown right. 6. If the coupling coefficient of the local OSC coil is small and an anti- resonance point of approximately 100MHz is present or the stray capacitance across pins 24 and 23 is large, a parasitic oscillation of approximately 100MHz may occur in the buffer output (pin 24). In this case, connect a capacitance of approximately 30pF across pin 24 and GND. 7. AM OSC coi] Generally speaking, the following should be noted. Avoid winding with loose coupling between primary side and secondary side (especially SWI, SH2). To put it concretely, the pot core type is better than the screw core type which is loose in coupling. This prevents the local OSC frequency from turning third resonance frequency related to the coupling coefficient. 8. Resistance across pin 8 and ¥, If pin 8 is used for the stop signal (SD) only, without using LED, it is recommended to fix resistance Ry across: pin 8 and GND ‘to be 51kohms to 100kohns. 9. To prevent whistle from worsening, make the pattern of AM output pin 14 as short as possible. 4. =e wm Input/Output Admittance Parameter ney. iF vit | 40.7mHz = [Parancter [Frequency] ~ Aeerort at EEE TwHe ‘SoDkH 1F vir? | Sook Wo.2012-4/13.LAl267 Test Circuit : FM, AN-Mi aM poet 2-Fy ip a oat. eu | ons coe Bar ome oe eee i Pa neoe negpa 3 — “op = podem Er oom mace gee Oe 1 Biome eas ‘Unit (resistance: 9, capacitance: F) 4, ew tnpt/output Characteristios To = Wie Poteotton, ouepstaioas-75inr vers aa 3 a 0 aL amy ¢ t Zz | 3 40 Bs ge z Bw i Bigg L1=10.
