This EVM includes 7 TPD2E1B06DRL’s in various configurations for testing. Five TPD2E1B06DRL’s are configured for IEC61000-4-2 compliance testing, one TPD2E1B06DRL is configured for 4-port s-parameter analysis, and one is configured for throughput on USB 2.0 Type A connectors for throughput analysis. Additionally, two of the TPD2E1B06DRL’s for ESD testing also allow the capture of clamping waveforms during an ESD event. This user's guide includes setup instructions, schematic diagrams, a bill of materials, and printed-circuit board layout drawings for the evaluation module. 1 INTRODUCTION Texas Instrument’s TPD2E1B06DRL evaluation module helps designers evaluate the operation and performance of the TPD2E1B06DRL device. The TPD2E1B06DRL is a dual channel ESD protection device in a small DRL package which offers IEC61000-4-2 Level 4 compliant ESD protection. The 1 pF line capacitance is suitable for a wide range of applications. The TPD2E1B06DRL is characterized for operation over an ambient air temperature range of -40°C to 125°C. The EVM contains seven TPD2E1B06DRL’s. A single TPD2E1B06DRL (U1) is configured with two USB2.0 Type A female connectors (J5 & J6) for capturing Eye Diagrams. The data lines are connected to TPD2E1B06DRL’s IO protection pins. A single TPD2E1B06DRL (U2) is configured with 4 SMA (J1 – J4) connectors to allow 4-port analysis with a vector network analyzer. Five TPD2E1B06DRL’s (U3 – U7) are configured with test points for striking ESD to the protection pins, two of those (U5 & U6) also have SMB (J7 & J8) connectors for capturing clamping waveforms with an oscilloscope during ESD test. Caution must be taken when capturing clamping waveforms during an ESD event so as not to damage the oscilloscope. A proper procedure is outlined below in Section 3.4. Table 1.

Air Discharge — a method of testing in which the charged electrode of the ESD simulator approaches the DUT, and a spark to the DUT actuates the discharge. ESD simulator — a device that outputs IEC61000-4-2 compliance ESD waveforms shown in Figure 1 with adjustable ranges shown in Table 2 and Table 3. IEC61000-4-2 has 4 classes of protection levels. Classes 1 – 4 are shown in Table 2. Stress tests should be incrementally tested to level 4 as shown in Table 3 until the point of failure. If the DUT does not fail at 8kV, testing can continue in 2 kV increments until failure.

A generalized outline of the procedure given in IEC61000-4-2 is described here. IEC-61000-4-2 should be referred to for a more specific testing outline. Basic configurations for collecting S-parameters, Eye Diagrams, and ESD clamping waveforms are outlined as well. 3.1 U1 A single TPD2E1B06DRL (U1) is configured with two USB2.0 Type A female connectors (J5 & J6) for capturing Eye Diagrams. Using either J5 or J6 as input or output, attach to a USB2.0 compliant Eye Diagram tester setup for the intended application, either transmitter or receiver. 2 TPD2E1B06DRLEVM SLVU917 – August 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated SETUP www.ti.com 3.2 U2 TPD2E1B06DRL (U2) is configured with 4 SMA (J1 – J4) connectors to allow 4-port analysis with a vector network analyzer. Connect Port 1 to J1, Port 2 to J2, Port 3 to J3, and Port 4 to J4. This configuration allows for the following terminology in 4 port analysis: • S11: Return loss • S21: Insertion loss • S31: Near end cross talk • S41: Far end cross talk 3.3 U3 – U7 TPD2E1B06DRL (U3 – U7) can be used for destructive electrostatic discharge (ESD) pass/fail ESD strikes. Specifically, they can be used for both IEC-61000-4-2 air and contact discharge tests. The following procedure ensures proper testing setup and method for both discharge tests. Each IO has a Test Pad (TP1 – TP10) directly connected to it. 3.3.1 Test Method and Set-Up An example test setup is shown in Figure 2. Details of the testing table and ground planes can be found in the IEC 61000-4-2 test procedure. Ground the EVM using the banana connector labeled GND (J9). Discharge the ESD simulator on any of the Test Points TP1 – TP10. Contact and air-gap discharge are tested using the same simulator with the same discharge waveform. While the simulator is in direct contact with the test point during contact, it is not during air-gap. Figure 2.

After each incremental level, if the IV curve of the ESD protection diode shifts ±0.1V, or leakage current increases by a factor of ten, then the device is permanently damaged by ESD. 3.4 U5 & U6 Two TPD2E1B06DRL’s (U5 & U6) also have SMB (J7 & J8) connectors for capturing clamping waveforms with an oscilloscope during an ESD strike. Caution must be taken when capturing clamping waveforms during an ESD event so as not to damage the oscilloscope. 3.4.1 Oscilloscope setup Without a proper procedure, capturing ESD clamping waveforms exposes the oscilloscope to potential voltages higher than the rating of the equipment. Proper methodology can mitigate any risk in this operation. Recommended equipment: • Minimum of 1GHz bandwidth oscilloscope. • Either of the following: – 2 10X 50Ω attenuators and 0 Ω resistors (already installed {R1 & R2}). – 1 10X 50Ω attenuator and 150 Ω resistors (to be installed at R1 & R2). • 50 Ω shielded SMB cable. Procedure In order to protect the oscilloscope, attenuation of the measured signal is required. Here are two possible procedures for testing U5: 1. Using two 10X attenuators: • Attach two 10X attenuators to the oscilloscope channel being used. • Attach the 50 Ω shielded SMB cable between J7 and the attenuator. • Set the scope attenuation factor to 100X. • Set the oscilloscope to trigger on a positive edge for (+) ESD and a negative edge for (-) ESD strikes. The magnitude should be set to 20V. • Following Section 3.3.1, strike contact ESD to TP5. 2. Using one 10X attenuator: • Install 150 Ω resistors in R1 and R2. • Attach one 10X attenuator to the oscilloscope. • Attach the 50 Ω shielded SMB cable between J7 and the attenuator. • Set the scope attenuation factor to 40X. • Set the oscilloscope to trigger on a positive edge for (+) ESD and a negative edge for (-) ESD strikes. The magnitude should be set to 20V. • Following Section 3.3.1, strike contact ESD to TP5. Recommended settings for the time axis is 20 ns/div and for the voltage axis is 10V division. The same procedure above can be applied to U6 by striking ESD on TP8 and connecting the 50Ω shielded SMB cable to J8. The voltage levels of the ESD applied to TP5 & TP8 should not exceed +/- 8 kV while capturing clamping waveforms. 4 TPD2E1B06DRLEVM SLVU917 – August 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated BOARD LAYOUT www.ti.com 4 BOARD LAYOUT This section provides the TPD2E1B06DRLEVM board layout.
