† _{All typical values are at VDD = 5 V, TA = 25°C.}
NOTES: 3. Glitch impulse does not include clock and data feedthrough. The – 3-dB test bandwidth is twice the clock
rate.
4. Unless otherwise specified, test conditions for RS343-A video signals are those listed in the
Recommended Operating Conditions, using external voltage reference VREF = 1.235 V and RSET = 523Ω.
When using the internal voltage reference, RSET may need to be adjusted to meet these limits.
