SLLSEK0A – DECEMBER 2014 – REVISED FEBRUARY 2015

Typical Application (continued)

9.2.1 Design Requirements

For this design example, three TPD6F002-Q1 devices are being used in an 18-bit display panel application. This

will provide a complete ESD and EMI protection solution for the display connector.

Given the display panel application, the following parameters are known.

DESIGN PARAMETER

VALUE

Signal range on all pins except GND

0 V to 5 V

Operating Frequency

50 MHz

9.2.2 Detailed Design Procedure

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

following:

•

Signal range of all the protected lines

•

Operating frequency

•

Crosstalk response

9.2.2.1 Signal Range on All Protected Lines

The TPD6F002-Q1 has 6 identical protection channels for signal lines. All I/O pins will support a signal range

from 0 to 5.5 V.

9.2.2.2 Operating Frequency

The TPD6F002-Q1 has a 100 MHz –3 dB bandwidth, which supports the operating frequency for this display.

9.2.2.3 Crosstalk Response

The TPD6F002-Q1 has a –47 dB near-side crosstalk attenuation at 100 MHz, sufficient for this display.
