F1975
Description
The F1975 Digital Step Attenuator (DSA) is a product in IDT’s Glitch-Free TM DSA Family, which is optimized for the demanding requirements of CATV and satellite systems. It operates in the frequency range of 5MHz to 3000MHz. This device is offered in a pact 4mm 4mm, 20-pin Thin QFN package with a 75Ω impedance for ease of integration.
Advantages
Digital step attenuators are used in receivers and transmitters to provide gain control. The F1975 is a 6-bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (+64d Bm IIP3). The device has pinpoint attenuation accuracy. Most importantly, the F1975 includes IDT’s Glitch-Free TM technology, which results in low overshoot and ringing during most significant bit (MSB) transitions.
- Glitch-Free TM technology protects the power amplifier or analog-to-digital converter (ADC) from damage during transitions between attenuation states
- Extremely accurate...
