® VERSACLOCK 3S - 5P35021 Evaluation Board Figure 8. Evaluation Board Schematic (IV) Signal Termination Options Termination options for Differential Output 1 - 2 in the evaluation board are displayed in Figure 9. The termination circuits are designed to optionally terminate the output clocks in LVPECL, LVDS, LVCMOS and HCSL signal types by populating (or not-populating) some resistors. -
Page 9: Orderable Part Numbers
Note: ** The differential output is applicable to LPHCSL which is the default configuration of the board. * The single-ended output is applicable to LVCMOS which is the default configuration of the board. Contact IDT if user wants to change termination configuration to support other output signal types. Orderable Part Numbers The following evaluation board part numbers are available for order. - Page 10 IDT or any third parties.
