      Standby: 5mW (typ.)
   – IDT70121/70125L
      Active: 675mW (typ.)
      Standby: 1mW (typ.)
◆ Fully asychronous operation from either port
◆ MASTER IDT70121 easily expands data bus width to 18 bits or
   more using SLAVE IDT70125 chip
◆ On-chip port arbitration logic (IDT70121 only)
Busy output Flag on Master; Busy input on Slave
◆ INT Flag for port-to-port communication
◆ Battery backup operation—2V data retention

Description : Ripple Attenuator Modules

Product Highlights
Ripple attenuator modules may be connected to VI-200 or VI-J00 converters, FlatPACs, MegaPACs, MasterModules or MegaModules, with output voltages from 5 to 50V, to limit output noise to less than 3mV peak-to-peak at loads up to 20A. Combining active and passive filtering, the VI-RAM attenuates both low frequency input power source fundamental and harmonics, and high frequency switching components in the frequency range of DC to 20 MHz, while exhibiting efficiencies of 93-99%. No adjustments are required, and remote sense and output voltage trim features are retained.

Features
■ Reduces Output Ripple to <3 mV pp
■ Compatible with any VI-200/VI-J00-based Product: 5 to 50Vdc Output
■ Full Attenuation Up to 20A
■ No Adjustments Required
■ 93-99% Efficiency
■ Converter Sense, Trim, Overvoltage and Overcurrent Retained
■ Size: 2.28" x 2.4" x 0.5" (57,9 x 61,0 x 12,7)
■ CE Marked
