Clock Kunobva
Paunenge uchishandisa iyo DC890 controller inofanirwa kupa yakaderera jitter 2.5VP-P (Kana VCCIO iri munzvimbo ye3.3V, wachi. amplitude inofanirwa kuve 3.3VP-P.) sine kana sikweya wave kuJ1. Iyo wachi yekupinza ndeye AC yakabatanidzwa saka iyo DC nhanho yechiratidzo chewachi haina kukosha. Jenareta yewachi senge Rohde & Schwarz SMB100A inokurudzirwa. Kunyangwe jenareta yewachi yakanaka inogona kutanga kuburitsa inooneka jitter pane yakaderera frequencies. Saka inokurudzirwa kune yakaderera sample mareti kugovera pasi yakakwira frequency wachi kune yaunoda kupinza frequency. Chiyero chenguva yewachi kusvika kuhuwandu hwekushandura inoratidzwa muTebhu 1. Kana kuisa kwewachi kuchizofambiswa nemafungiro, zvinokurudzirwa kuti 49.9Ω terminator (R5) ibviswe. Inononoka kusimuka mipendero inogona kukanganisa iyo SNR yekushandura pamberi pepamusoro amplitude yakakwirira frequency kuisa masaini.
Data Output
Parallel data inobuda kubva mubhodhi iri (0V kusvika 2.5V nekusarudzika), kana isina kubatana neDC890, inogona kuwanikwa neanoongorora logic, yobva yapinzwa muspredishiti, kana pasuru yemasvomhu zvichienderana nekuti imhando ipi yedhijitari yekugadzirisa inodiwa. . Neimwe nzira, iyo data inogona kudyirwa yakananga kudunhu rekushandisa. Shandisa pini 50 yeP1 kubata data. Iyo data inogona kusungirirwa uchishandisa inodonha kumucheto kwechiratidzo ichi. Mune verify mode maviri anodonha mipendero anodiwa kune yega data sample. Iyo data inobuda chiratidzo mazinga paP1 anogona zvakare kuchinjwa kuita 0V kusvika 3.3V kana dunhu rekushandisa richida yakakwira voltage. Izvi zvinoitwa nekufambisa VCCIO (JP3) kune iyo 3.3V chinzvimbo.
