ISDB-T 1-Segment Tuner

Offers -99dBm to 0dBm Dynamic Range at Only 80mW Power Consumption


The MAX2163 low-IF tuner IC is designed for use in 1-segment ISDB-T applications. The MAX2163 directly converts UHF band signals to a low-IF using a broadband I/Q downconverter. The operating frequency range covers the UHF band from 470MHz to 806MHz.

The MAX2163 includes LNAs, RF variable gain amplifiers, I and Q downconverting mixers, a baseband variable gain amplifier, and a low-IF filter. The MAX2163's variable gain amplifiers provide in excess of 100dB of control range.

The MAX2163 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 MAX2163 features a 2-wire I²C-compatible serial-control interface. A low-power standby mode is available that shuts down the signal path leaving the control interface and register circuits active. Additionally, an external pin can shut down the entire device.

The MAX2163 is specified for operation in the extended -40°C to +85°C temperature range and is available in a 5mm x 5mm x 0.8mm, 28-pin thin QFN, lead-free plastic package with exposed paddle (EP).
