EEPROM PROGRAMMABLE 2.5V PROGRAMMABLE SKEW PLL CLOCK DRIVER
NOTE:
1. These inputs are normally wired to VDD, GND, or left floating. Internal termination resistors bias unconnected inputs to VDD/2. If these inputs are switched dynamically after powerup,
the function and timing of the outputs may be glitched, and the PLL may require additional tLOCK time before all datasheet limits are achieved.

NOTES:
1. See RECOMMENDED OPERATING RANGE table.
2. VDIF specifies the minimum input differential voltage (VTR - VCP) required for switching where VTR is the "true" input level and VCP is the "complement" input level. Differential mode
only. The DC differential voltage must be maintained to guarantee retaining the existing HIGH or LOW input. The AC differential voltage must be achieved to guarantee switching
to a new state.
3. VCM specifies the maximum allowable range of (VTR + VCP) /2. Differential mode only.
4. For single-ended operation, in differential mode, REF[1:0]/VREF[1:0] is tied to the DC voltage VREF[1:0].
5. Voltage required to maintain a logic HIGH, single-ended operation in differential mode.
6. Voltage required to maintain a logic LOW, single-ended operation in differential mode.
7. Typical values are at VDD = 2.5V, VDDQN = 1.5V, +25°C ambient.
8. The reference clock input is capable of HSTL, eHSTL, LVEPECL, 1.8V or 2.5V LVTTL operation independent of the device output. (See Input/Output Selection table.)
