摘要:DiSEqC LNB SUPPLY and REGULATOR VOLTAGE CONTROL
Intended for analog and digital satellite receivers/sat-TV, sat-OC cards, the INN8193 is a monolithic voltage regulator and interface IC, packaged in TSSOP16EP, specifically designed to provide the 13/18V power supply with 650mA loading and the 22kHz tone signaling to the LNB down-converter in the antenna dish or to the multi-switch box.
   INN8193 consists of a boost converter and a low-noise linear regulator along with the circuitry required for tone injection and pin controllable interface. The device makes the total LNB supply design simple, efficient and compact with low external component count
   The external modulation input (EXTM, pin4) can accept a tome modulated DiSEqC command and transfer it symmetrically to the output to meet DiSEqC 1.x protocol.
