UNISONIC TECHNOLOGIES CO., LTD LB8102 Preliminary CMOS IC www.unisonic.com.tw 1 of 4 Copyright © 2015 Unisonic Technologies Co., Ltd QW-R123-019.a DISEqC SWITCH IC  DESCRIPTION The integrated circuit UTC LB8102 DiSEqC switch IC is specially designed for satellite multi-switch It receives and decodes DiSEqC command, Tone Burst and output control for signal switch. The UTC LB8102 DiSEqC switch IC provides four-switch control. A 22KHz DiSEqC control signal input to UTC LB8102 DiSEqC IC can select one of four sw itches. This feature is used as Satellite Position/Option Switch Control usually in LNB application. The built in decode process is fully compatible with DiSEqC protocol about committed switch.  FEATURES * Single supply voltage 3.9V~5V. * Support DiSEqC 1.0/ 1.1 and Tone Burst commend * Selectable 4x1 and 2x1 application. * Drives up to four switches. * Position and option witch commend. * SOP8 surface mount package SOP-8  ORDERING INFORMATION Ordering Number Package Packing LB8102G-S08-R SOP-8 Tape Reel  MARKING
