w w w . D a t a S h e e t . c o . k r RTM875N-397 AC Performance Measurement Report Measurement Equipment : Clock Rise Time / Fall Time Are Measured by Tektronix® 6804B with Single-ended Probe – Mainframe with 8.0GHz Bandwidth – Mainframe with 20GS/s Sampling Rate – P7240 Active Probe with 4.0GHz Bandwidth (input: 1.0pF / 20K-ohm) Clock Jitter & Duty Cycle Are Measured by Tektronix® 6804B with Differential Probe – P7330 Differential Active Probe with 3.5GHz Bandwidth (input: 0.5pF / 100K-ohm) – Tektronix® Jitter Analysis 3® Jitter Measurement Software Measurement Environment : – Test board Measurement Item : Differential Clock – Slew_Rise & Slew_Fall – Vcross & ΔVcross – Cycle to Cycle jitter – Vmax & Vmin – Duty Cycle Single-end Clock – Slew_Rise & Slew_Fall – Duty Cycle Cycle to Cycle jitter Measurement Summary From the measurement shown as follows, RTM875N-397 works good and meets all CLK Spec. Measurement Signal: 1.CPU0 CLOCK 4.PCIE6 CLOCK 7.PCI CLOCK 10.Phase jitter 2. CPU1 CLOCK 5.PCIE11 CLOCK 8.USB CLOCK 3.SATA CLOCK 6. DOT96 CLOCK 9. REF CLOCK D a t www.DataSheet.co.kr Measurement Condition #1 Slew_Rise & Slew_Fall Of Differential Waveform : Rise and fall slew rate are measured differential waveform between +150mV and -150mV on the rising and falling edges of the clock. (Reference CK505 spec page.19 / 20) #2 Vcross Of Differential Waveform : Absolute cross point= 0.3 ~0.55 V (Reference CK505 spec page.19 / 20) #3 ΔVcross Of Differential Waveform : Absolute ΔVcross <140 mV (Reference CK505 spec page.19 / 20) Datasheet pdf - http://www.DataSheet4U.net/ www.DataSheet.co.kr #4 Cycle to Cycle jitter : Absolute Cycle to Cycle jitter <85 ps (Reference CK505 spec page.19 / 20 & JEDEC JESD65-A page.13) #5 Vmax & Vmin : Vmax < 1.15 V and Vhigh > -0.3V. Measure the Vmax & Vmin value by using Tektronix Scope “Vmax ” & “Vmin” function. (Reference CK505 page.18) #6 Duty Cycle : Duty cycle specification is between 45 and 55%. (Reference CK505 page.19) Datasheet pdf – http://www.DataSheet4U.net/ www.DataSheet.co.kr #7 Slew_Rise & Slew_Fall Of Single Waveform: Rise and fall slew rate are measured single waveform between 0.8V and 2.0V on the rising and falling edges of the clock. (Reference CK505 spec page.20~22) #8 Duty Cycle Of Single Waveform : Duty cycle specification is between 45 and 55%. (Reference CK505 page.20~23) #4 Cycle to Cycle jitter : (Reference CK505 spec page.20~23 & JEDEC JESD65-A page.13) Datasheet pdf – http://www.DataSheet4U.net/ www.DataSheet.co.kr 1. CPU0 CLOCK Slew_Rise Specification Measured Result 2.5~8 V/ns See #1 3.519 V/ns Vmax Specification Measured Result < 1.15V See #4 0.890 V Slew_Fall 2.5~8 V/ns See #1 3.716 V/ns Vmin > -0.3V See #4 -0.023 V Vcross 300~550 mV See #3 392 ~ 428 mV Duty Cycle 45%~55% See #2 50.81 % ΔVCROSS ΔVCROSS <140 mV See #3 36 mV C-C jitter < 85 ps See #2 42 ps Slew_Rise & Slew_Fall Cycle to Cycle jitter & Duty Cycle Vcross & ΔVcross Vmax & [...]
