AD9516-3BCPZ-REEL7 IC CLOCK PLL/VCO 2GHZ 64LFCSP

Incazelo

I-AD9516-31 ihlinzeka ngomsebenzi wokusabalalisa wewashi wemiphumela eminingi ngokusebenza kwe-subpicosecond jitter, kanye ne-onchip PLL ne-VCO.I-on-chip VCO ishuna isuka ku-1.75 GHz iye ku-2.25 GHz.Uma uthanda, i-VCO/VCXO yangaphandle efika ku-2.4 GHz ingasetshenziswa.I-AD9516-3 igcizelela i-jitter ephansi nomsindo wesigaba ukuze kukhuliswe ukusebenza kwesiguquli sedatha, futhi ingazuzisa ezinye izinhlelo zokusebenza ngomsindo wesigaba onzima nezimfuneko ze-jitter.I-FUNCTIONAL BLOCK DIAGRAM REFIN REF1 REF2 CLK LF SWITCHOVER AND MONITOR PLL DIVIDER KANYE NE-MUXs I-CP VCO STATUS MONITOR I-LVPECL LVPECL LVPECL LVDS/CMOS LVDS/CMOS SERIAL PORT KANYE NE-DIGITAL LOGIC AD95016-OUT3 OUT3DIV OUT34 OUT3 OUT3 OUT3DIV OUT34 OUT3 OUT3 OUT3 DIVIC OUT64 OUT3 OUT3 OUT3 DIVPECL I-DIV/Φ DIV/Φ DIV/Φ DIV/Φ DIV/Φ DIV/Φ Δt Δt Δt Δt 06422-001 Umfanekiso 1. I-AD9516-3 ifaka imiphumela eyisithupha ye-LVPECL (ngamapheya amathathu) kanye nemiphumela emine ye-LVDS (ngamapheya amabili) .Okukhiphayo ngakunye kwe-LVDS kungahlelwa kabusha njengemiphumela emibili ye-CMOS.Okuphumayo kwe-LVPECL kusebenza ku-1.6 GHz, okuphumayo kwe-LVDS kusebenza ku-800 MHz, futhi okuphumayo kwe-CMOS kusebenza ku-250 MHz.Okuphumayo ngakunye kunezihlukanisi ezivumela kokubili isilinganiso sokuhlukanisa nokubambezeleka okumaholo (noma isigaba) ukuthi zisethwe.Ububanzi bokuhlukaniswa kokuphumayo kwe-LVPECL ngu-1 kuya ku-32. Imiphumela ye-LVDS/CMOS ivumela uhla lokuhlukanisa lufike ku-1024. I-AD9516-3 itholakala ku-LFCSP engu-64 futhi ingasetshenziswa kusukela ku-3.3 eyodwa V ukunikezwa.I-VCO yangaphandle, edinga ububanzi be-voltage enwetshiwe, ingafakwa ngokuxhuma iphampu ye-charge (VCP) ukuya ku-5 V. Ukunikezwa kwamandla okuhlukile kwe-LVPECL kungaba ukusuka ku-2.5 V ukuya ku-3.3 V (okungenani).I-AD9516-3 icaciswe ukuthi isebenze ebangeni elijwayelekile lezimboni lika-−40°C kuya ku-+85°C.
