• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

AC Electrical Characteristics
† Timing is over recommended temperature & power supply voltages.
‡ Typical figures are at 25
* Contents of Connection Memory are not lost if the clock stops, however, ST-BUS outputs go into the high impedance state.
NB: Frame Pulse is repeated every 512 cycles of C4i.
