SET-TOP BOX SERIES LNB CONTROLLER AND POWER SUPPLY IC
Description
The ZLPM8014 is a power management and control solution for
satellite set-top boxes (STBs). Based on an efficient boost converter
the ZLPM8014 provides a power supply within the range of 11V to
21V as well as all the control signals required by a single port satellite
Low Noise Block (LNB). The ZLPM8014 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 and with the minimal
external components, the ZLPM8014 provides a high performance,
cost efficient solution.
