MAX9257 Maxim, MAX9257 Datasheet - Page 47

• Manufacturer Part Number: MAX9257
• Description: The MAX9257 serializer pairs with the MAX9258 deserializer to form a complete digital video serial link
• Manufacturer: Maxim

The MAX9257/MAX9258 ESD tolerance is rated for
Human Body Model, Machine Model, IEC 61000-4-2
and ISO 10605. The ISO 10605 and IEC 61000-4-2
standards specify ESD tolerance for electronic sys-
tems. LVDS outputs on the MAX9257 and LVDS inputs
on the MAX9258 meet ISO 10605 ESD protection and
IEC 61000-4-2 ESD protection. All other pins meet the
