Features • Highly integrated mixer/oscillator PLL and IF AGC amplifier for multi band analog/digital terrestrial tuners and/or cable tuners • Low phase noise PLL frequency synthesizer • AGC output level detect with digital controlled TOP threshold • >50 dB Desired/Undesired ratio without pre filtering • Separate analog and digital IF outputs • >41 dB IF AGC Control range • Power down modes to support power reduction initiatives • Four independent GPO • 48 pin QFN Package Applications • DVB-T receiver systems • ISDB-T receiver systems • DVB-C cable receiver systems • Terrestrial analog receivers Description The ZL10060 is a 3 band MOPLL with IF AGC amplifier. It down-converts the RF channel to a standard IF followed by filtering and IF AGC amplification for the digital channel. Each band consists of a low noise preamplifier/mixer and local oscillator with an external varactor tuned tank circuit. An IF level detector is included for control of the RF AGC. The Take Over Point and time constant are both programmable. The ZL10060 has high signal level handling performance providing excellent performance in the presence of high level unwanted signals. All chip control is via I2C bus. If higher performance is required, an alternative part, ZL10063 is available with image reject down conversion.
