10. Output drivers will drive CMOS logic levels into a CMOS load.
11. As an alternative to supplying a 2.3-to-2.7V input, this pin may be left floating.
13. Attenuation measured at the demodulator output of an HP3785B with input jitter equal to 3/4 of
14. Jitter measured at the demodulator output of an HP3785A using a measurement
15. Output jitter increases significantly when attenuator input jitter tolerance is exceeded.
8. In Host Mode, pin 23 is an open drain output and pin 25 is a tristate output.
9. Pins 17 and 18 of the CS61535A are digital inputs in the Extended Hardware Mode.
