Overview
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.
 Lowest insertion loss for best SNR APPLICATIONS  Base Station 2G, 3G, 4G, TDD radio cards  Repeaters and E911 systems  Digital Pre-Distortion  Point to Point Infrastructure  Public Safety Infrastructure  WIMAX Receivers and Transmitters  Military Systems, JTRS radios  RFID Handheld and Portable Readers  Cable Infrastructure ORDERING INFORMATION Omit IDT prefix 0.
