Описание
The MAX2112ETI+ is a complete, direct conversion tuner for DVB-S2 applications in 28 pin thin QFN-EP package. It is a low-cost, direct-conversion tuner IC is designed for satellite set to p and VSAT applications. The IC is intended for 8PSK and Digital Video Broadcast (DVB-S2) applications. The MAX2112 directly converts the satellite signals from the LNB to baseband using a broadband I/Q down converter. The operating frequency range extends from 925MHz to 2175MHz. The device includes an LNA and an RF variable-gain amplifier, I and Q down converting mixers and baseband low pass filters with programmable cut-off 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 DVB-S2 demodulators. The MAX2112 includes fully monolithic VCOs, as well as a complete fractional-N frequency synthesizer.
• Supply voltage range from 3.13V to 3.47V
• Operating temperature range from -40°C to +85°C
• Fully monolithic VCOs and a complete fractional-N frequency synthesizer
• On-chip crystal oscillator with a buffered output for driving additional tuners and demodulators
• I2C 2-wire serial interface
• Address pin for multi-tuner applications
• Low power standby mode
• Low phase noise of -97dBc/Hz at 10KHz
• High dynamic range from -75dBm to 0dBm
• Integrated variable baseband low pass filter bandwidth range from 4MHz to 40MHz
