MAX2117CTI+T
Complete, Direct-Conversion Tuner for MMDS Applications
General DescriptionThe MAX2117 low-cost, direct-conversion tuner is
intended for receiving MMDS transmissions in the
470MHz to 1000MHz band. The MAX2117 is designed
to be used in consumer set-top boxes and is compati-
ble with most DVB-S demodulators.
The MAX2117 directly converts the QPSK broadcast
signals from the antenna to baseband using a broad-
band I/Q downconverter. The tuner provides differential
I and Q outputs to the demodulator IC.
The device includes an LNA and an RF variable-gain
amplifier, I and Q downconverting mixers, and baseband
lowpass filters with programmable cutoff frequency
control and digitally controlled baseband variable-gain
amplifiers. Together, the RF and baseband variable-gain
amplifiers provide more than 80dB of gain-control range.
The IC is compatible with virtually all QPSK demodulators.
The MAX2117 includes fully monolithic VCOs, as well as
a complete frequency synthesizer. Additionally, an on-
chip 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. The IC fea-
tures a VCO autoselect (VAS) function that automatically
selects the proper VCO. For multituner applications, the
device can be configured to have one of two 2-wire
interface addresses. A low-power standby mode is
available whereupon the signal path is shut down while
leaving the reference oscillator, digital interface, and
buffer circuits active, providing a method to reduce
power in single and multituner applications.
The MAX2117 is the most advanced MMDS tuner avail-
able today. The low noise figure eliminates the need for
an external LNA. A small number of passive compo-
nents are needed to form a complete MMDS front-end
solution. The tuner is available in a very small 28-pin
thin QFN package.
