Voltage measurements are with respect to ground (V

) unless otherwise stated.
Note 1:
Supply current and device power is for 8 ports in E1 mode. Typical values are with V
and V
at nominal, with all output pins
loaded with half the rated capacitance (as given in the AC Characteristics section) and with the two UTOPIA clocks as inputs.
Maximum values are with V
and V
at + 5% (2.625 V and 3.465 V), with all output pins loaded with the full rated
capacitance, and the two UTOPIA clocks as outputs.
Note 2:
UDT mode supply current and device power includes 1800 cells of CPU/OAM traffic in both directions, and no discards of non-
AAL1 cells, giving Look-Up Table reads of 1 800 reads/second.
Note 3:
SDT mode supply current and device power includes 1800 cells of CPU/OAM traffic in both directions, and sufficient discards of
non-AAL1 cells to bring Look-Up Table reads to 1 000 000 reads/second.
