MAX2121ETI+ Products
The MAX2121ETI+ is a complete direct conversion L-band tuner in 28 pin TQFN package. This low cost, direct conversion tuner IC is designed for satellite set-top and VSAT applications. The device directly converts satellite signals from LNB to baseband using broadband I/Q downconverter. The device includes LNA and RF variable gain amplifier, I and Q downconverting mixers, baseband lowpass filters and digitally controlled baseband variable gain amplifiers. Together, the RF and baseband variable gain amplifiers provide more than 80dB of gain control range. The device includes fully monolithic VCOs as well as complete fractional-N frequency synthesizer. Additionally an on-chip crystal oscillator is provided along with buffered output for driving additional tuners and demodulators. The IC has VCO autoselect (VAS) function that automatically selects proper VCO. A small number of passive components are needed to form complete broadband satellite tuner DVB-S2 RF front end solution.

Feature

  • Supply voltage range from 3.13V to 3.47V
  • Operating temperature range from -40°C to 85°C
  • Monolithic VCO, low phase noise of -97dBc/Hz at 10KHz and no calibration required
  • Supply current of 148mA (receive mode, bit STBY = 0) and 3mA (standby mode, bit STBY = 1)
  • High dynamic range from -75dBm to 0dBm and address pin for multituner applications
  • 123.75MHz integrated LP filters and low power standby mode
  • Operating frequency range extends from 925MHz to 2175MHz
  • Low noise figure eliminates need for an external LNA
