SP6001-0XUTG-1 Datasheet, PDF (1/1 Pages) Littelfuse – LCD and camera interfaces in mobile devices are vulnerable to EMI from the cellular band

Silicon Protection Arrays
Application Guide
LCD and Camera Interfaces (Mobile)
Considerations:
● LCD and camera interfaces in mobile devices are vulnerable to EMI from the cellular band
→ Frequencies between 800-3000MHz should be attenuated to prevent distortion on the display
● The pixel clocks vary depending upon the display size but the frequency will typically fall between 5-65MHz
→ This corresponds to data rates between 10-60Mbps and with these speeds line capacitances need to be
considered
→ In the majority of applications line capacitances of 20-40pF will not cause signal integrity issues
● The protection schemes below for data lines Dx are only examples and will vary with the particular application
