DESCRIPTION

The FM1236 front-end is designed to receive both TV and FM stereo signals in the PC Multimedia environment. The units are available with separate 75Ω inputs for TV and FM broadcast reception. The input connectors available are either standard phono or F type. The tuning, bandswitching and antenna selection are made through the I 2C bus. The front-end covers the TV bands from 55.25 MHz to

801.25 MHz, inclusive of the Japanese TV bands from

91.25 MHz to 765.25 MHz. The FM band covers the standard 87.50 MHz to 108.00 MHz and also the Japanese FM band (76.00 MHz to 91.00 MHz). An RDS decoder can be connected to the AF-MPX output. The FM1236 meets the input immunity and radiation requirements of the FCC, DOC and JIS. The FM1236 consists of a TV tuner, an FM radio tuner and an IF section, all designed on a single PCB. The front-end is assembled in a metal housing made of a rectangular tin-plated steel frame, with front and rear covers, which have soldered contacts to the frame. The two phono or F antenna connectors (female) are mounted on one side of the frame for the TV/FM signal inputs. All other connections are made via pins at the bottom. The TV IF section uses an intercarrier SAW filter, followed by a true-synchronous vision IF demodulator (PLL) IC. The analog AFC voltage is fed to the 5-level A/D converter in the PLL tuning IC, so that the AFC status can be read via the I 2C-bus. In the FM radio mode, the level detector and AFT functions are provide for the auto-search routines. The level detector and AFT status can be read from the A/D bits in the status-byte. The mute function is also provided to suppress the audio output signal, if required. The tuner AGC for both TV and FM radio operation, is generated with a novel AGC detector which measures the IF signal level directly at the tuner IF output terminals. As opposed to the conventional AGC detector, this new circuit allows a higher take-over level and offers superior immunity against tuner overload. The demodulation of the TV sound (4.5 MHz) and FM IF (10.70 MHz) is done with a PLL demodulation circuit contained in the IF IC. In the FM radio mode, the multiplexed AF signal is then channelled to a stereo decoder IC which extracts the left/right analog signals. The multiplexed audio signal is also available at pin 25 to support RDS or BTSC implementations. The 2 nd IF sound output is provided to connect external (analog 2 carrier or digital) stereo processing.

APPLICATION INFORMATION

A detailed description of the I2C-bus specification, with applications, is given in brochure‘‘The I2C-bus and how to use it’’. This brochure may be ordered using the code number 9398 393 40011. WRITE mode Note 1. A = Acknowledge. ADDRESS SELECTION VS = +5 V (PLL supply voltage) Note 1. If the AS pin is left floating, the internal bias will automatically set the address to C2. PROGRAMMABLE DIVIDER SETTINGS (BYTES 1 AND 2) Divider ratio: N=1 6 ×{ fRF(pc) + fIF(pc)}, where (pc) is picture carrier and fRF and fIF are expressed in MHz fosc = N ⁄16 (MHz). C ONTROL BYTE Charge pump settings: CP = 1, for fast tuning CP = 0, for moderate speed tuning with slightly better residual oscillator FM. It is recommended to set CP = 1 at all times in the TV mode. In the FM radio mode, set CP = 1 only during the search tuning. Once the wanted channel is obtained, set CP = 0 to get the best signal-to-noise ratio. Test mode settings: T2 = T1 = 0; T0 = 1, for normal operation.
