Type number Code number Origin letter of factory Change code Year and week code DESCRIPTION The new FQ1236L/F H-3 belongs to the new family of small size frontends, specially developed for LCD-TV application where a low noise and high performance is required. The FQ1236L/F H- 3 combines the functions of an all-band TV tuner, and a Quasi-Split Sound IF (QSS) demodulation unit. 2 The frontends have a built-in digital (I C) PLL tuning system. A DC-DC converter circuit is built-in in the FQ1236L MK3 to synthesize the tuning voltage required, thus making the frontend a true 5V device. The footprint is identical to the Mk3, but the overall thickess is lower. There is a minor difference in software setting compared to FQ1236L Mk3. See Pg 12 and 13.

Example 2 : To tune to M system program at Ch A2 (471.25 MHz, FM Trap Bypassed) 2 LOADING OF I C BUS The FQ1236L MK3 contains series impedances in the SCL and SDA as shown in the diagram below. Both lines also have capacitive loads of C= 22 pF max. Care must be taken to ensure that the total load on the bus does not exceed that as 2 mentioned in the brochure "The I C-Bus Specifications". AUDIO EMPHASIS The audio de-emphasis (75 us) is set by the bits C5 and C6 C5=0 de-emphasis OFF C5=1 de-emphasis ON C6=1 50us C6=0 75 us Please note that de-emphasis should always be switched off for BTSC or SAP applications. This to avoid such information riding above the audio spectrum but on the AF output from being filtered off by the deemphasis filter. CVBS LOAD / TUNING VOLTAGE SUPPLY A video buffer is built into the frontend to enable the unit to drive a 75 Ω load directly (e.g. into the SAA711x directly). A DC-DC converter for providing the required tuning voltage supply is already built into the FQ1236L MK3 PIP APPLICATION The FQ1236L has a second user-defined address for the IF circuit. By setting a 2K2 resistor at pin 10, the IF IC address is set to # 84. In the same manner, with a 1K resistor to ground at pin 6, the tuner is set to an address of # C0. The other FQ1236L Mk 5 remains unchanged with an adresss of # C2 and # 86 respectively. An example is shown below.
