1. Functionality of pins 23 and 25 depend on mode. See Host mode and Hardware mode description.
2. Output drivers will output CMOS logic levels into CMOS loads.
3. As an alternative to supplying 2.3 - 2.7 V (Midrange logic level) to these pins, they may be left open.
4. Referenced pin numbers are for the PLCC package. Refer to
1. Typical figures are 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. The Jitter Attenuator is in the receive path or disabled.
3. Guaranteed by characterization; not subject to production testing.
4. Circuit attenuates jitter at 20 dB/decade above the corner frequency.
