1 / 24 page  F1956 Datasheet 7-Bit 0.25 dB Wideband Digital Step Attenuator 1 to 6000 MHz F1956, Rev 2 04/08/2016 GENERAL DESCRIPTION This document describes the specification for the F1956 Digital Step Attenuator. The F1956 is part of IDT’s Glitch-FreeTM family of DSAs optimized for the demanding requirements of Base Station (BTS) radio cards and numerous other non-BTS applications. This device is offered in compact 5 mm x 5 mm 32-pin package with 50 input and output impedance for ease of integration into the radio or RF system. COMPETITIVE ADVANTAGE The F1956 offers very high reliability due to its construction from a monolithic silicon die in a QFN package. The insertion loss is very low with minimal distortion. Additionally the device is designed to have extremely accurate attenuations levels. These accurate attenuation level improves system SNR and/or ACLR by ensuring system gain is as close to targeted level as possible. Also, the very fast settling time in parallel mode is ideal for fast switching systems. Finally, the device is Glitch-FreeTM with less than 2 dB of ringing across the attenuation range in stark contrast to competing DSAs that glitch as much as 10 dB during MSB state changes. Lowest insertion loss for best SNR Glitch-FreeTM technology to protect PA or ADC during transitions between attenuation states. Extremely accurate attenuation levels Ultra low distortion MSL1 and 2000 V HBM ESD ORDERING INFORMATION FEATURES Serial & 7-bit Parallel Interface 31.75 dB Range 0.25 dB steps Glitch-FreeTM: low transient overshoot 500 ns settling time Ultra linear > 64 dBm IIP3 Low Insertion Loss < 1.7 dB @ 4 GHz Attenuation error < ±0.2 dB @ 4 GHz Bi-directional RF use 3.3 V or 5 V Supply 1.8 V or 3.3 V control logic Low Current Consumption: 350 μA typical -40 °C to +105 °C operating temperature 5 mm x 5 mm Thin QFN 32 pin package FUNCTIONAL BLOCK DIAGRAM Decoder RF1 RF2 D[6:0] SPI Bias A[2:0] CLK DATA LE VMODE Glitch-FreeTM Glitch-FreeTM Part# Details Part# Freq Range (MHz) Resolution / Range (dB) Control IL (dB) Pinout F1950 150 - 4000 0.25 / 31.75 Parallel & Serial 1.3 PE43702 PE43701 F1951 100 - 4000 0.50 / 31.5 Serial Only 1.2 HMC305 F1952 100 – 4000 0.50 / 15.5 Serial Only 0.9 HMC305 F1953 400 – 4000 0.50 / 31.5 Parallel & Serial 1.3 PE4302 DAT-31R5 F1956 1 - 4000 0.25 / 31.75 Parallel & Serial 1.4 PE43705, PE43712, RFSA3715 F1912 1 – 4000 0.50 / 31.5 Parallel & Serial 1.6 PE4312 PE4302 F1956NBGI8 Green Tape & Reel |
