80 / 86 page  80 Altera Corporation Mercury Programmable Logic Device Family Data Sheet Tables 44 and 45 describe the Mercury device’s external timing parameters. Notes to Tables 44 and 45: (1) These timing parameters are sample-tested only. (2) All timing parameters are either to and/or from pins, including global clock pins. Table 44. Mercury External Timing Parameters Notes (1), (2) Symbol Parameter Conditions tINSU Setup time with global clock at IOE register tINH Hold time with global clock at IOE register tOUTCO Clock-to-output delay with global clock at IOE register C1 = 35 pF tINSUPLL Setup time with PLL clock at IOE input register tINHPLL Hold time with PLL clock at IOE input register tOUTCOPLL Clock-to-output delay with PLL clock at IOE output register C1 = 35 pF Table 45. Mercury External Bidirectional Timing Parameters Notes (1), (2) Symbol Parameter Conditions tINSUBIDIR Setup time for bidirectional pins with gobal clock at IOE input register tINHBIDIR Hold time for bidirectional pins with global clock at IOE input register tOUTCOBIDIR Clock-to-output delay for bidirectional pins with global clock at IOE output register C1 = 35 pF tXZBIDIR Synchronous IOE output enable register to output buffer disable delay C1 = 35 pF tZXBIDIR Synchronous IOE output enable register output buffer enable delay C1 = 35 pF tINSUBIDIRPLL Setup time for bidirectional pins with PLL clock at IOE input register tINHBIDIRPLL Hold time for bidirectional pins with PLL clock at IOE input register tOUTCOBIDIRPLL Clock-to-output delay for bidirectional pins with PLL clock at IOE output register C1 = 35 pF tXZBIDIRPLL Synchronous IOE output enable register to output buffer disable delay with PLL C1 = 35 pF tZXBIDIRPLL Synchronous IOE output enable register output buffer enable delay with PLL C1 = 35 pF |
