Maxim's Single-Conversion Silicon Tuner Enables Superior Reception of Analog and Digital TV Broadcasts
Maxim has introduced the MAX3542 single-conversion silicon tuner for hybrid (analog and digital) applications. This device employs a single downconversion step from RF to 36MHz to provide artifact-free reception of analog signals and high-quality reception of digital signals. Competing solutions use either a dual-conversion architecture that requires two external filters or a direct-to-low-IF scheme that suffers from poor image rejection.
The MAX3542 overcomes these impairments and offers a typical image rejection of 70dB while requiring a single external SAW filter. Offering superior performance and a compact footprint, the MAX3542 is ideal for TVs, PCs, and set-top boxes.This fully integrated solution is an ideal replacement for canned tuners. The MAX3542 has a standard 36MHz IF that is compatible with most digital and analog demodulators. Additionally, the IC integrates tracking filters, a crystal oscillator circuit, a synthesizer, and an IF VGA to save space and simplify design over canned-tuner implementations. Drawing a mere 230mA (typ) from a single 3.3V supply, the MAX3542 strikes an excellent balance between performance and power consumption.
