The devices include fully monolithic VCOs, as well as a complete frequency synthesizer. Additionally, an onchip crystal oscillator is provided along with a buffered output for driving additional tuners and demodulators. Synthesizer programming and device configuration are accomplished with a 2-wire serial interface. For multituner applications, each device can be configured to have one of eight possible 2-wire interface addresses. Simplifying the interface to low-voltage CMOS demodulators, the MAX2116/MAX2118 incorporate two 2.85V regulated outputs for pulling up open-drain interface connections, thus preventing noisy 3V rails from corrupting the sensitive analog signal of the tuners. The MAX2116/MAX2118 devices are the most versatile family of DBS products available. With both singleended and differential baseband outputs, these devices are compatible with virtually all QPSK/8-PSK demodulators. The tuners are available in a very small 40-pin thin QFN package.
