IDTF1912NCGI

6 Bit Digital Step Attenuator GENERAL DESCRIPTION This document describes the specification for the IDT F1912 Digital Step Attenuator. The F1912 is part of a family of Glitch-FreeTM DSAs optimized for the demanding requirements of Base Station (BTS) radio cards and numerous other non-BTS applications. These devices are offered in a compact 4mm x 4mm 20 pin QFN package with 50Ω impedances for ease of integration. COMPETITIVE ADVANTAGE Digital step attenuators are used in receivers and transmitters to provide gain control. The F1912 is a 6bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (> +60 dBm IIP3). The device has pinpoint accuracy. Most importantly, the F1912 includes IDT’s Glitch-FreeTM technology, which results in low overshoot and ringing during MSB transitions.  Glitch-FreeTM technology so PA or ADC will not be damaged during when transitions.  Extremely accurate with low distortion.  ...
