The MAX2163A low-IF tuner IC is designed for use in 1- and 3-segment ISDB-T applications. The MAX2163A directly converts VHF and UHF band signals to a low-IF using a broadband I/Q downconverter. The operating frequency range covers the VHF-L band from 90MHz to 108MHz, VHF-H band from 170MHz to 222MHz, and the UHF band from 470MHz to 806MHz.
The MAX2163A includes LNAs, RF variable gain amplifiers, I and Q downconverting mixers, a baseband variable gain amplifier, and a low-IF filter. The MAX2163A’s variable gain amplifiers provide in excess of 102dB of control range.
The MAX2163A also includes fully monolithic VCOs as well as a complete frequency synthesizer including an on-chip crystal oscillator and output buffer. The device operates with a crystal from 32MHz to 36MHz.
The MAX2163A features both 2-wire I2C and 4-wire SPI™/MICROWIRE™-compatible serial-control interfaces. A low-power standby mode is available that shuts down the signal path leaving the control interfaces and register circuits active. Additionally, an external pin can shut down the entire device.
The MAX2163A is specified for operation in the extended -40°C to +85°C temperature range and is available in either a 2.85mm x 3.1mm, lead-free, wafer-level package (WLP) or a 6mm x 6mm x 0.8mm, 40-pin thin QFN, lead-free plastic package with exposed paddle (EP).
