What happens if input edge rates to the transmitter exceed datasheet specifications?
The device will still function with input edge rates faster than the datasheet specification; however, it is not recommended for these reasons: • Extremely fast edge rates tend to ring and have over / undershoot. It creates more noise into the chip resulting in more jitter. If the over or undershoot exceeds the ABS-MAX datasheet specification, the ESD protection path could turn on causing excess current to flow. • Extremely fast edge rates have a very fast dv/dt that couples more noise into the chip and creates more common-mode noise on the LVDS outputs. This results in higher EMI levels. However, the data is not impacted as it is differential.
