is asserted. After VDD is stable and the RST pin is subsequently

released, a fully clocked reset sequence must follow. This power

supply sequence ensures that analog functions and all level setting

DACs receive the proper configuration information during the digital

partition reset sequence.

The power supplies must be removed in the reverse order.

Note that VREF and the high speed transmission line termination

pins (VTTDx, VTTCx) are all part of the analog partition, but they

are not treated as supplies. VREF can be managed independent

of VCC and VEE, provided its potential never goes outside those of

the VEE and VCC supply buses to prevent ESD protection diodes

from becoming forward biased. The VTTDx and VTTCx pins do not

have this restriction relative to VCC and VEE, but they must never go

outside the absolute maximum ratings as measured with respect to

PGND.
