• Manufacturer Part Number: cy7b995ait
• Description: 2.5/3.3v 200-mhz High-speed Multi-phase Pll Clock Buffer
• Manufacturer: Cypress Semiconductor Corporation.

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
for a description of input-to-output and output-to-output phase
relationships.
Table 10. PE/HD Settings
The CY7B995 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
(V
the output power supplies.

7. LL disables outputs if TEST = MID and sOE# = HIGH.
8. 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.
