ANADIGICS APS3611
The APS3611 offers a special frequency/ gain profile, which compensates for inband signal attenuation caused by MOCA line filters. The small surface mount QFN packaging makes this device ideal for use in today’s set-top boxes, televisions and video tuner cards requiring multiple-tuner solutions.FEATURES
AP S3 61 1APPLICATIONS
● Analog/Digital and All-Digital CATV Set-Top Boxes with Multiple Tuners and Multimedia Over Coax Alliance (MOCA) Functionality● Multiple-Tuner TVs, TV Tuner Cards and Broadband Media Centers This APS3611 active splitter from ANADIGICS accepts a broadband RF input from 50 MHz to 870 MHz and splits the signal to provide two broadband RF outputs with minimal degradation of quality. The single-package surface mount device amplifies the input using highly linear, low noise amplification stages, and couples the amplified signal to two separate output paths that each can drive either analog video, digital video or digital S26 Package 12 Pin QFN 3 mm x 3 mm x 1 mm data tuners. Requiring a single voltage supply of +5 V, and operable down to +3.3 V, the active splitter is manufactured using ANADIGICS’ highly reliable GaAs MESFET process. PRODUCT
