NOTES:
2. Test conditions for RS343-A video signals (unless otherwise specified), see Section 3.2, Recommended
Operating Conditions using external voltage reference Vref = 1.235 V, RSET = 523
. When using the
internal voltage reference, RSET may need to be adjusted in order to meet these limits.
3. Glitch area does not include clock and data feedthrough. The – 3-dB test bandwidth is twice the clock rate.
4. Pipeline delay from pixel port depends on Latch Control Register setting. Value shown is for LCR = 0x06.
