1. Functionality of pin 23 and 25 depends 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 to these pins, they may be left open.
4. Listed pins are for the PLCC package. Refer to
“
Pin Assignments and Signal Descriptions
”
on page 8
for the 44-pin QFP
package.

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.
