Table 4. MF Calculation
In addition to determining whether the outputs synchronize to
the rising or the falling edge of the reference signal, the 3-level
PE/HD pin controls the output buffer drive strength as
indicated in
Table 6
.
The CY7B9950 features split power supply buses for Banks 1
and 2, Bank 3 and Bank 4, which enables the user to obtain
both 3.3V and 2.5V output signals from one device. The core
power supply (VDD) must be set a level that is equal or higher
than on any one of the output power supplies.
Governing Agencies
The following agencies provide specifications that apply to the
CY7B9950. The agency name and relevant specification is
listed below.

LL disables outputs if TEST = MID and sOE# = HIGH.
When 4Q[0:1] are set to run inverted (HH mode), sOE# disables these outputs HIGH when PE/HD = HIGH or MID, sOE# disables them LOW when PE/HD = LOW.
