Surface Mount Package Applications - DOCSIS 3.0 Data Cable Modems and E-MTAs - CATV Set Top Boxes S29 Package 28-Pin QFN 5 mm x 5 mm x 1 mm The ARA2017 supports output power levels of +64 d Bm V while minimizing harmonic, distortion, and output noise levels. Its precision attenuator provides up to 58 d B of attenuation in 2 d B increments. The attenuator setting is programmed via a 3-wire serial interface, as is the output stage current, a feature which allows the device to be operated in reduced power modes for extended backup battery life in E-MTA applications. The ARA2017 is offered in a 28pin 5 mm x 5 mm x 1 mm QFN package. PRODUCT DESCRIPTION The ARA2017 is a highly linear, high output power, programmable gain amplifier optimized for DOCSIS 3.0 cable modem and E-MTA applications. Using a low noise input amplification stage and an ultra linear output driver amplifier, the device generates extremely low distortion products at the high output power levels required by DOCSIS 3.0 signals. Its balanced circuit design provides superior harmonic performance and an integrated digitally-controlled, multiple-stage precision step attenuator enables system solutions to meet DOCSIS power step accuracy requirements.
