VIDEO CHARACTERISTICS

The following tables and figures describe the DC/AC char-

acteristics of the CS5530 video interface. It is divided into

the following categories:

• Recommended Operating Conditions

• Miscellaneous Operating Characteristics

• Analog Output Rise/Settle Times

• Setup/Hold and Delay Times

Additionally, Figure 5-8 is provided showing a typical

video connection diagram.

Notes 1 and 3

Notes: 1. Timing measurements are made with a 75 ohm doubly-terminated load, with VEXTREF = 1.235V and

RSET = 732 ohms.

2. 10% to 90% of full-scale transition.

3. Full-scale transition: time from output minimum to maximum, not including clock and data feedthrough.
