MIVAR 17V3 TVD Chassis TV3883 TUNER

Tuner and Frequency synthesizer + prescaler and Video IF and Sound 1 IF In One module.

Frequency synthesizer + prescaler with SDA3302 (SIEMENS)
Video IF with TDA8341 (PHILIPS)
Mixer + osc with TDA5330T (PHILIPS)


TDA5330T VHF, UHF and Hyperband mixer/oscillator for TV and VCR 3-band tuners

GENERAL DESCRIPTION
The TDA5330T is a monolithic integrated circuit that performs the band A, band B and band C mixer/oscillator functions
in TV and VCR tuners. This device gives the designer the capability to design an economical and physically small 3-band
tuner which will be capable of meeting the most stringent requirements e.g. FTZ or FCC. The tuner development time
can be drastically reduced by using this device.
Features
· Balanced mixer with a common emitter input for band A
· Amplitude-controlled oscillator for band A
· Balanced mixer with common base input for band B and C
· Balanced oscillator for band B and C
· Local oscillator buffer output for external prescaler
· SAW filter preamplifier with an output impedance of 100 W
· Bandgap voltage stabilizer for oscillator stability
· Electronic bandswitch

· VCR Tuners

GENERAL DESCRIPTION
The TSA5511 is a single chip PLL frequency synthesizer
designed for TV tuning systems. Control data is entered
via the I2C-bus; five serial bytes are required to address
the device, select the oscillator frequency, programme the
eight output ports and set the charge-pump current. Four
of these ports can also be used as input ports (three
general purpose I/O ports, one ADC). Digital information
concerning those ports can be read out of the TSA5511 on
the SDA line (one status byte) during a READ operation.
A flag is set when the loop is “in-lock” and is read during a
READ operation. The device has one fixed I2C-bus
address and 3 programmable addresses, programmed by
applying a specific voltage on Port 3. The phase
comparator operates at 7.8125 kHz when a 4 MHz crystal
is used.
