8.2.1 Design Requirements

For this design example, three TPD6F202 devices are used in an 18-bit display panel application. This

application provides a complete ESD and EMI protection solution for the display connector. For the display

panel application, the following parameters are in shown Table 8-1.

Table 8-1. Design Parameters

DESIGN PARAMETER

VALUE

Signal range on all pins except GND

0 V to 5 V

Data Rate

200 Mbps

ESD Protection Level

IEC 61000-4-2 Level 4

8.2.2 Detailed Design Procedure

To begin the design process, some design parameters must be decided; the designer needs to know the

operating frequency and the signal range on all the protected lines.

8.2.2.1 Signal Range on All Protected Lines

The TPD6F202 has 6 identical protection channels for signal lines. All I/O pins will support a signal range from 0

to 5.5 V.

8.2.2.2 Data Rate

The TPD6F202 has a 108-MHz, –3-dB bandwidth, which supports the data rate for this display.

8.2.2.3 ESD Protection Level

The contact and air-gap ratings of ± 25 kV for TPD6F202 exceeds the IEC 61000-4-2 Level 4 rating of ± 8-kV

contact and ± 15-kV air-gap ratings.

9 Power Supply Recommendations

The TPDxF202 device is a passive ESD-protection device, and therefore, does not require a power supply. Take

care to avoid violating the maximum-voltage specification to ensure that the device functions properly. The IO

lines can tolerate up to 6-V DC.
