6 Bit Digital Step Attenuator

1 MHz to 4000 MHz

GENERAL DESCRIPTION

FEATURES

 Serial & 6 bit Parallel Interface

This document describes the specification for the IDT

F1912 Digital Step Attenuator. The F1912 is part of a

family of Glitch-Free^TMDSAs optimized for the

demanding requirements of Base Station (BTS) radio

cards and numerous other non-BTS applications.

These devices are offered in a compact 4mm x 4mm

20 pin QFN package with 50Ω impedances for ease of

integration.

 31.5 dB Control Range

 0.5 dB step

 Glitch-Free^TM, low transient overshoot

 3.0 V to 5.25 V supply

 1.8 V or 3.3 V control logic

 Attenuation Error < 0.22 dB @ 2 GHz

 Low Insertion Loss < 1.6 dB @ 2 GHz

 Ultra linear IIP3 >+59.5 dBm

 IIP2 = +110 dBm typical

COMPETITIVE ADVANTAGE

 Stable Integral Non-Linearity over temperature

 Low Current Consumption 550 µA typical

 -40 °C to +105 °C operating temperature

 4mm x 4mm Thin QFN 20 pin package

Digital step attenuators are used in Receivers and

Transmitters to provide gain control. The F1912 is a

6-bit step attenuator optimized for these demanding

applications. The silicon design has very low insertion

loss and low distortion (> +60 dBm IIP3.) The device

has pinpoint accuracy. Most importantly, the F1912

includes IDT’s Glitch-Free^TMtechnology which results in

low overshoot & ringing during MSB transitions.
