NOTES:
1. The 732mV peak-to-peak input pulse level is specified to allow consistent, repeatable results in an automatic test equipment (ATE) environment. This device meets the VDIF (AC)
specification under actual use conditions.
2. A 1082mV crossing point level is specified to allow consistent, repeatable results in an automatic test equipment (ATE) environment. This device meets the VX specification
under actual use conditions.
3. In all cases, input waveform timing is marked at the differential cross-point of the input signals.
4. The input signal edge rate of 1V/ns or greater is to be maintained in the 20% to 80% range of the input waveform.

NOTES:
1. See RECOMMENDED OPERATING RANGE table.
2. For 2.5V LVTTL single-ended operation, the RxS pin is tied HIGH and REF[1:0]/VREF[1:0] is left floating. If TxS is HIGH, FB/VREF2 should be left floating.
3. 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.
4. VCM specifies the maximum allowable range of (VTR + VCP) /2. Differential mode only.
5. For single-ended operation, in differential mode, REF[1:0]/VREF[1:0] is tied to the DC voltage VREF[1:0].
6. Voltage required to maintain a logic HIGH, single-ended operation in differential mode.
7. Voltage required to maintain a logic LOW, single-ended operation in differential mode.
8. Typical values are at VDD = 2.5V, VDDQ = VDD, +25°C ambient.
9. 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.)
