F1977
DESCRIPTION
This document describes the specification for the F1977 Digital Step Attenuator. The F1977 is part of a family of Glitch-Free TM DSAs optimized for the demanding requirements of CATV and Satellite systems. These devices are offered in a pact 5 mm x 5 mm 32 pin QFN package with 75 Ω impedances for ease of integration.
PETITIVE ADVANTAGE
Digital step attenuators are used in Receivers and Transmitters to provide gain control. The F1977 is a 7-bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss, low distortion (+64 d Bm IIP3) and pinpoint attenuation accuracy. Most importantly, the F1977 includes IDT’s Glitch-Free TM technology which results in low overshoot & ringing during MSB transitions.
Lowest insertion loss for best SNR
Extremely accurate attenuation levels.
Ultra low distortion. Glitch-Free TM technology to protect PA or ADC during transitions between attenuation states.
