6 / 41 page  Product Description 2 - 6 KTS6027-2, KTS6029-2 Wireless Components Specification, July 2001 2.1 General Description The KTS6027-2, KTS6029-2 device combines a digitally programmable phase locked loop (PLL), with a mixer-oscillator block including two balanced mixers and oscillators for use in TV and VCR tuners. The PLL block with four selectable chip addresses forms a digitally programm- able phase locked loop. With a 4 MHz quartz crystal, the PLL permits precise setting of the frequency of the tuner oscillator up to 1024 MHz in increments of 31.25, 50, 62.5 or 166.7 kHz. The tuning process is controlled by a micropro- cessor via an I2C bus. The device has four output ports. A flag is set when the loop is locked. It can be read by the processor via the I2C bus. The mixer-oscillator block includes two balanced mixers (one mixer with high- impedance input and one mixer with a balanced low-impedance input), two fre- quency and amplitude-stable balanced oscillators for LOW/MID and HIGH, an IF amplifier, a low-noise reference voltage source, and a band switch. 2.2 Features General s Suitable for analog and digital terrestrial TV tuner s Compatible with KTS6027-S or KTS6029-S in normal mode s New features in extended mode s Full ESD protection Mixer/Oscillator s High impedance mixer input for LOW/MID band s Low impedance mixer input for HIGH band s 4 pin oscillator for LOW/MID band s 4 pin oscillator for HIGH band IF-Amplifier s single ended IF preamplifier s 75 Ω output impedance PLL s PLL with short lock-in time s High voltage VCO tuning output s Fast I2C bus s 4 NPN bandswitch buffers s Internal LOW-MID/HIGH switch |
