MAX2163
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 broad-
band I/Q downconverter. The operating frequency
range covers the UHF band from 470MHz to 806MHz.
The MAX2163 includes LNAs, RF variable gain ampli-
fiers, I and Q downconverting mixers, a baseband vari-
able 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 I
2
C-compatible serial-
control interface. A low-power standby mode is avail-
able 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).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
