Family of RF Devices Targets Broadband and CATV Markets

SAN JOSE, CA -- Integrated Device Technology, Inc. (IDT) expands its RF portfolio with the addition of a new family of digital step attenuators (DSAs) optimized for the demanding requirements of the broadband and CATV markets. The ultra-high-linearity 75-ohm DSAs feature IDT's industry-first Glitch-Free™ technology for enhanced performance.

The F1975 and F1977 deliver very low insertion loss and distortion, and have much higher power handling with pinpoint attenuation accuracy than competing devices, giving customers the performance needed to achieve higher data rates in their system. The Glitch-Free capabilities help to ensure low overshoot and ringing during MSB transitions, and the 75-ohm impedance offers ease of integration in the target applications. Additionally, the F1977 is the industry's first monolithic silicon, 75-ohm Glitch-Free, 7-bit DSA, enabling customers to achieve 0.25dB gain control while maintaining industry-leading RF performance.

The F1975 and F1977 are fully production released with inventory available at authorized IDT resellers for sampling and production. The F1975, priced at $1.16 each in a lot of 10,000, is offered in a compact 4 x 4 mm 20-TQFN package; the F1977, priced at $1.45 each in a lot of 10,000, comes in a compact 5 x 5 mm 32-QFN package.
