Negative supply pins.
Differential output pairs. LVPECL interface levels.
Differential output pairs. LVPECL interface levels.
Core supply pins.
Output enable. When HIGH, forces true outputs (PCIEXTx) to go
Pulldown LOW and the inverted outputs (PCIEXCx) to go HIGH. When LOW,
outputs are enabled. LVCMOS/LVTTL interface levels.
Differential output pairs. LVPECL interface levels.
Differential output pairs. LVPECL interface levels.
Differential output pairs. LVPECL interface levels.
Pulldown Frequency select pin. LVCMOS/LVTTL interface levels.
Pulldown
Bypass select pin. When HIGH, the PLL is in bypass mode, and the
device can function as a 1:6 buffer. LVCMOS/LVTTL interface levels.
Analog supply pin. Requires 24Ω series resistor.
Pullup Selects PLL Bandwidth input. LVCMOS/LVTTL interface levels.
