General Description
Intended for analog and digital satellite receivers/sat-TV, sat-OC cards, the G5165 is a monolithic voltage regulator and interface IC, specifically designed to provide the 14V/19V power supply with high efficiency and the 22KHz EXTM signaling to the LNB down-converter in the antenna dish or to the multi-switch box.
G5165 consists of a BOOST converter and a low-noise linear regulator along with the circuitry required for EXTM 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 pin) can accept a tone modulated DiSEqC command and transfer it symmetrically to the output to meet DiSEqC 1.x protocol.
Applications
● LNB Power supply For DVB-S/S2/ABS
● Digital STB
● Satellite TV cards
