Test Set-Up and Description

Equipment List: Agilent PNA E8364B/X4421B Vector Network Analyzer

Agilent PLTS version 2.5 software Tektronix TDS8000 Digital Sampling Oscilloscope Rhode & Schwarz SMP02 Signal Generator Advantest D3186 Pulse Pattern Generator TDA Systems IConnect version 3.5 software

Tests Performed: TDR Impedance: trise = 50ps (10%-90% ) Near-end and Far-end Crosstalk trise = 50ps (10%-90% ) Eye Pattern (6.25Gbps and 12 Gbps) Insertion Loss (from 50 MHz to 20 GHz) Return Loss (from 50 MHz to 20 GHz) Isolation (from 50 MHz to 20 GHz)

TDR Impedance: The daughter card side is driven. All immediate neighbors are terminated with 50Ω loads.

Crosstalk: All signals are driven from the daughter card side. Listening on the daughter card side is NEXT. Listening on the backplane side is FEXT. All immediate neighbors are terminated with 50Ω loads.

Total crosstalk is reported as the square root of sum of squares of the maximum value of all the individual contributions. (see detailed description below, page 15)

Eye Pattern: All signals are driven from the daughter card side. All immediate neighbors are terminated with 50Ω loads.

Insertion Loss/Return Loss/ Isolation: All immediate neighbors are terminated with 50Ω loads.

Port 1 is on the daughter card. Port 2 is on the backplane and corresponds to Port 1. Port 3 is on the daughter card. Port 4 is on the backplane and corresponds to Port 3. Ports 1 and 3 are the inputs of the differential pair. Ports 2 and 4 are the outputs of the differential pair.

Convention for defining risetime: Measurement risetime is defined as risetime of the signal at the end of the PCB trace going into the connector

3dB BW is calculated as follows: Measured 2X 3 dB cal trace bandwidth = 3.2 GHz Calculated 1X 6 dB Cal trace bandwidth = 10 GHz Risetime Degradation = .35/10 GHz = 35 ps Risetime to the Connector = [ (System Risetime)2 + (Risetime Degradation)2] ½ = [ (35 ps)2 + (35 ps)2] ½ = 49 ps (10-90%)= 30ps (20-80%)

Eye Patterns using Tx/Rx grouping In order to estimate real channel noise , using TX/RX assignments, Molex has developed a methodology to estimate Jitter and eye height/width closure when applying adjacent channel noise to a near quiet line. This is done by measuring the Sparameters of the quiet line, and all the isolation, or noise coupling Sparameters from the quiet line to the nearest neighbors of interest. The Agilent ADS Ptolemy model allows Sparameters to be coupled into the quiet channel, using pulse adders Input signal conditions: PRBS: 211-1 Voltage: +/- 200 mv Pre/Post Emphasis = none Column Column Column Worst case Tx/Rx 8 pair grouping

Frequency Domain Analysis Overview: The Molex CTV is designed to evaluate connector performance is a variety of test conditions. To derive maximum performance understanding, with various signaling conditions, both long and short via scenarios are recorded in the VNA data below. Signal pairs A2, A3, C3, G1, G2, G3, J1, L1 and L2, show I/L and R/L performance with longer via stubs while pairs A1, C1, C2, J2, J3 and L3 show improved performance due to shorter stubs.

Isolation (6-pair Pattern)

The four Isolation tables below provide the minimum isolation values, in dB, for a victim signal line in all four of the mixed mode parameters. The measurements were taken with the VNA attached to the victim signal lines on the motherboard, and the “aggressor” lines on the daughter card. The tables below show the worst-case dB isolation:

Victim: J2 Aggressors: J1, J3, L1, L2, L3, G1, G2, G3 Victim: G2 Aggressors: G1, G3, J1, J2, J3, C1, C2, C3

Driven Differential Mode/Listen Differential Mode Minimum Isolation (dB) Freq < 3Ghz Freq < 6 GHz Freq < 10GHz

Signal J2 -23.47 -19.66 -16.54 G2 -25.38 -21.45 -20.27

Driven Differential Mode/Listen Common Mode

Minimum Isolation (dB) Freq < 3Ghz Freq < 6 GHz Freq < 10GHz

Signal J2 -26.72 -25.59 -25.57 G2 -28.78 -28.16 -20.80

Driven Common Mode/Listen Differential Mode

Minimum Isolation (dB) Freq < 3Ghz Freq < 6 GHz Freq < 10GHz

Signal J2 -26.68 -23.89 -23.24 G2 -25.50 -25.80 -28.65
