3. TECHNICAL BRIEF
3.13.5 TV out Interface
The display data is converted to video with video-encoder according to CCIR-601 and sampled by 10-
bit DAC and transmitted over an analog pad as a composite video signal.
This mode is used in a system where ZR345X is connected gluelessly to a TV screen that requires
real-time display data.
ZR345X generates TV signal according to the NTSC and PAL standards.
The TVDATA pin can drive a full video level signal directly into a 75 terminated TV cable.
