More Info
The IDT F1953 is part of a family of Glitch-FreeTM DSAs optimized for the demanding requirements of communications Infrastructure. These devices are offered in a compact 4x4 QFN package with 50 impedances for ease of integration.
Digital step attenuators are used in Receivers and Transmitters to provide gain control. The IDT F1953 is a 6-bit step attenuator optimized for these demanding applications. The silicon design has very low insertion loss and low distortion (> +60 dBm IP3I.) The device has pinpoint accuracy and settles to final attenuation value within 400 ns. Most importantly, the F1953 includes IDT’s Glitch-FreeTM technology which results in less than 0.5 dB of overshoot ringing during MSB transitions. This is in stark contrast to competing DSAs that glitch as much as 10 dB. - Lowest insertion loss for best SNR
- Glitch-FreeTM when transitioning – won’t damage PA or ADC
- Extremely accurate with low distortion
