A Product Line of Diodes Incorporated ZLPM8014 SET-TOP BOX SERIES LNB CONTROLLER AND POWER SUPPLY IC Description System Diagram 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. 2 Controlled by an I C compatible interface and with the minimal external components, the ZLPM8014 provides a high performance, cost efficient solution. Applications Features High System Efficiency with Energy Saving Standby Mode Single Tuner Satellite Set-Top Boxes Efficient Boost Converter and LDO Provide an Accurate High Current LNBs Adjustable Power Supply for LNBs Stability with Minimal Current LNBs High Accuracy Output Overload and Temperature Satellite PC Cards Provides a Protected Output of up to 750mA (continuous) TVs with Integrated Satellite Tuners Programmable Current Limit for System Flexibility Hybrid Set-Top Boxes Optional Current Boost Mode. 150% of Imax for 65ms Suitable for Digital and Analog Satellite Systems Designed for Stability with Low Power LNBs Provides Standard Voltage / Tone and DiSEqC Control Signals and has a V Voltage Boost for SMW Applications pol Internal Tone Generator for DiSEqC Control and Traditional Band Switching Tone Maintains Shape Across all Load Conditions Internal Reliable Tone Detector for DiSEqC 2.0 Systems 2 Controlled by I C interface and Additional Logic Control for Tone Built in Multiple Diagnostics and Protection for IC and LNB Protection Minimal External Components for a Simple, Reliable and Cost Effective Solution Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
