if Integrated Da Circuit Systems, Inc. Product Family Brief SAW FILTERS FOR BROADBAND ACCESS GENERAL DESCRIPTION This family of SAW (surface acoustic wave) filters provides exceptionally low amplitude and phase ripple to meet the demanding needs of broadband access and cable router applications. The filters are available in standard bandwidths for international cable standards (typically from 6MHz to 8MHz) and custom bandwidths up to 7OMHz. Available center frequencies include standard and custom center frequencies up to 480MHz. SMT and DIP packages are available. APPLICATIONS * Digital Cable Television Systems * CMTS (Cable Modem Termination Systems) * Broadband Access (customized to unique requirements) * Satellite Communications SAW FILTERS FOR BROADBAND ACCESS FEATURES Standard bandwidths for international cable standards High selectivity for spurious rejection Low amplitude ripple for higher order modulation systems Standard and custom center frequencies up to 480MHz (Specify center frequency at time of order) Insertion loss ranging from 21.5cB to 27dB Packages inc.: SMT, DIP-FA or DIP-A, DIP-O, or DIP-BT TYPICAL RESPONSE SF0044BA01931S LT reer NM yy | ia Horizontal: 2.5 MHz/div; Center Frequency: 44 MHz Vertical: 10dB/div (amp); 1dB/div (amp); 20ns/div (delay) PartiNumber | Frequency Bandwidth Insertion | Package Primary (MHz) (MHz) Loss (dB) (mm) Application SF0036BA01932S 36 Bo. 215 SMT, 25x9 CMTS SF0038BA01943T 38 6. 25 _DIP-FA, 35x20 CMTS SF0044BA01930S 44 6 21.5 SMT, 25x9 (CMTS SFOO44BA0I931S._ 44 BMT, 25x9 CMTS SF0044BA55079T scant 55 22 DIP-BT, 27x12.6 CMTS _ SF0044BA01944T 44.125 8 25 DIP-FA, 35x20 Broadband Access SF0067BA01807T. 67.3 10.5 24 ___DIP-A, 35X20 Broadband Access SF0070BA02178T 70 ae 2 DIP-O, 22x13 EMTS SF0070CF51549T 29 35 27.
