NOTES: 3. Glitch impulse does not include clock and data feedthrough. The – 3-dB test bandwidth is twice the clock
rate.
4. Test conditions for RS343-A video signals (unless otherwise specified): Recommended Operating
Conditions, using external voltage reference VREF = 1.235 V, RSET = 523 Ω. When using the internal voltage
reference, RSET may need to be adjusted in order to meet these limits.
