Hi, I have an HCSL output (NB3N5573) that I want to use to drive the input of the LMK00725, that should accept HCSL.
I can't see any guidance on the termination needed to match the LVPECL, LVDS, HCSL, SSTL, LVHSTL compatible input of the LMK00725 to an HCSL signal.
Can you provide a recommended termination method?
Hi Vicente, Thank you for the support, appreciated.
I was reluctant to go with this diagram (fig 13) as it described the circuit during test - not necessarily the recommended configuration. Adding to my paranoia, the Application diagram (Fig 19) has for example, CLK1 (driven by LVPECL) input with 100R across the pairs and 180R to ground on each phase; but test diagrams for LVPECL (Fig 11&12) show a couple of different arrangements, both different to the application diagram (Fig 19).
I'll go with the configuration shared.
