JEDEC defines various classes and termination schemes for HSTL: I unterminated or symmetrically single parallel II source series or symmetrically double parallel III asymmetrically single parallel IV asymmetrically double parallel
What I'm missing is an answer to my question: Where to use which termination scheme? In my special case: Connecting one QDR SRAM to a FPGA by HSTL interface, providing different types of signals: differential (clocks), single-ended unidirectional (address, control) and single-ended bidirectional (data).
Who can assist?
