broad b and time d elay - a nalog - s m t 1 HMC911LC4B v 01.1211 broadband analog time delay, dc - 24 ghz general description features functional diagram the h m c911 l c4b is a broadband time delay with 0 to 70 ps continuously adjustable delay range. the delay control is linearly monotonic with respect to the differential delay control voltage (v d cp, v d c n ) and the control input has a modulation bandwidth of 1.6 g hz. the device provides a differential output voltage with constant amplitude for single-ended or differential input voltages above the input sensitivity level, while the output voltage swing may be adjusted using the v a c control pin. the h m c911 l c4b features internal temperature compensation and bias circuitry to mini - mize delay variations with temperature. a ll r f input and outputs of the h m c911 l c4b are internally termi - nated with 50 o hms to vcc, and may either be a c or d c coupled. o utput pins can be connected directly to a 50 o hm to vcc terminated system, while d c block - ing capacitors must be used if the terminated system input is 50 o hms to a d c voltage other than vcc. the h m c911 l c4b is available in r ohs-compliant 4x4 mm s m t package. very wide bandwidth: d c - 24 g hz continuous a djustable d elay r ange: 70 ps single- e nded or d ifferential o peration a djustable d ifferential o utput swing: up to 800mvp-p d elay control m odulation bandwidth: 1.6 g hz single supply: +3.3v 24 l ead ceramic 4x4mm s m t package: 16mm2 electrical specifcations, t a =+25c, vcc=3.3v, vac=2.6v, vee=gnd=0v typical applications the h m c911 l c4b is ideal for: ? synchronization of clock and data ? transponder design ? serial d ata transmission up to 32 g bps ? broadband test & m easurement ? r f a t e a pplications parameter conditions m in. typ. m ax. units power supply voltage %5 tolerance 3.13 3.3 3.47 v power supply current 460 530 ma time d elay r ange v d cp=3.9v, v d c n =3.3v @ 10 g hz 62 70 71 ps v d cp=3.9v, v d c n =3.3v @ 18 g hz 64 70 73 ps v d cp=3.9v, v d c n =3.3v @ 22 g hz 66 70 75 ps phase shift r ange v d cp=3.9v, v d c n =3.3v @ 10 g hz 210 250 d eg v d cp=3.9v, v d c n =3.3v @ 18 g hz 400 475 d eg v d cp=3.9v, v d c n =3.3v @ 22 g hz 515 595 d eg m aximum d ata r ate 32 g bps m aximum clock frequency 24 g hz for price, delivery and to place orders: hittite microwave corporation, 2 elizabeth drive, chelmsford, ma 01824 phone: 978-250-3343 fax: 978-250-3373 order on-line at www.hittite.com application support: phone: 978-250-3343 or apps@hittite.com
