general connection from CT2577 (Device) Interface Transformer (BIT) should short, heavy direct possible. Device pinout configured allowing conveniently connected. Pins Data_0, NData_0 Data_1, NData_1 respectively with Data_X connecting BIT. phase with following guidelines should observed: Power Ground planes should used. minimum each power pair should decoupled with 2.2uf tantalum 0.1uf ceramic both located close Device feasible. should located close pins possible. recommended that this distance less than inch. Ground plane allowed under these conductors pins (primary side). minimize effects high currents flowing through Device traces connecting each must greater than mils wide, equal length pass through vias. These connections should located side that Device package leads soldered center (CT) should connected directly ground plane. surface mount used ground plane connection should multiple filled vias. addition Device ground pins should connected close their respective possible. secondary side pins through interface with 1553 bus. Pins through isolation resistors forming "Direct Coupled" connection while pins "Transformer Stub Coupled". usually connected. Currents flowing secondary side 100-120ma with voltage levels high 26vpp. maximize signal integrity, impedance levels minimize crosstalk other signal traces interconnect 1553 connectors should direct possible with ground plane relieved along length traces. Matching trace lengths critical differences should minimized. Trace length should kept minimum. necessary extend these traces they, assuming above criteria observed, should longer than inches. limit mutual interactions signals crossing these conductors should kept minimum should right angles.
