1. Typical values are measured at 25
°
C and are for design aid only; not guaranteed and not subject to production testing.
2. Input signal to TCLK is jitter-free.
3. Guaranteed by characterization; not subject to production testing.
4. Circuit attenuates jitter at 20 dB/decade above the corner frequency.
