Description
6-bit Digital Step Attenuator 400 to 4000 MHz F1953 Datasheet GENERAL .
This document describes the specification for the IDTF1953 Digital Step Attenuator.
Features
* Glitch-FreeTM, < 0.6 dB transient overshoot
* Spurious Free Design
* 2.7 to 3.6 V supply
* Attenuation Error < 0.5 dB @ 2 GHz
* Low Insertion Loss < 1.4 dB @ 2 GHz
* Excellent Linearity >+60 dBm IP3I
* Fast settling time, < 400 ns
* Serial or Parallel Interface 31.5
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 durin
