A Product Line of Diodes Incorporated ZLPM8011 SET-TOP BOX SERIES SINGLE LNB CONTROLLER AND POWER SUPPLY IC Summary The ZLPM8011 is a power management and control solution for satellite set-top boxes (STBs). Based on an efficient boost converter the ZLPM8011 provides the power supply and all the control signals required by a single port satellite Low Noise Block (LNB). The ZLPM8011 includes an accurate 22kHz tone generator to provide DiSEqC™ control words or continuous tone for band switching control. To provide a reliable DiSEqC 2.0 solution the IC includes a DiSEqC detector with unwanted signal rejection. Controlled by an I2C™ compatible interface or logic inputs and with the minimal external components the ZLPM8011 provides a high performing, efficient cost efficient solution.
