1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. VDDQ and VDD internally operate independently. No power sequencing requirements
need to be met.
3. Not to exceed 3.6V.

NOTES:
1. Inputs are capable of translating the following interface standards. User can select between:
Single-ended 2.5V LVTTL levels
Single-ended 1.8V LVTTL levels
or
Differential 2.5V/1.8V LVTTL levels
Differential HSTL and eHSTL levels
Differential LVEPECL levels
2. Outputs are user selectable to drive 2.5V, 1.8V LVTTL, eHSTL, or HSTL interface levels when used with the appropriate VDDQ voltage.
3. 3-level inputs are static inputs and must be tied to VDD or GND or left floating. These inputs are not hot-insertable or over voltage tolerant.
4. Because the gate controls are asynchronous, runt pulses are possible. It is the user's responsibility to either time the gate control signals to minimize the possibility of runt
pulses or be able to tolerate them in down stream circuitry.
5. Pins listed as LVTTL inputs will accept 2.5V signals when RxS = HIGH or 1.8V signals when RxS = LOW or MID.

NOTE:
1. The INPUT/OUTPUT SELECTION Table describes the total possible combinations of input and output interfaces. Single-Ended (SE) inputs in a single-ended mode require the
A/VREF pin to be connected to GND. Differential Single-Ended (DSE) is for single-ended operation in differential mode, requiring a VREF. Differential (DIF) inputs are used only in
differential mode.

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, A/VREF is tied to the DC voltage VREF.
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, VDDQ = 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. The correct input interface table should be
referenced.
9. For differential mode (RxS = LOW), A and A/VREF must be at the opposite rail.

NOTES:
1. See RECOMMENDED OPERATING RANGE table.
2. For 1.8V LVTTL single-ended operation, the RxS pin is allowed to float or tied to VDD/2 and A/VREF is tied to GND.
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, A/VREF is tied to the DC voltage VREF. The input is guaranteed to toggle within ±200mV of VREF when VREF is constrained within
+600mV and VDDI-600mV, where VDDI is the nominal 1.8V power supply of the device driving the A input. To guarantee switching in voltage range specified in the JEDEC 1.8V
LVTTL interface specification, VREF must be maintained at 900mV with appropriate tolerances.
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 = 1.8V, +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. The correct input interface table should be
referenced.
10. This value is the worst case minimum VIH over the specification range of the 1.8V power supply. The 1.8V LVTTL specification is VIH = 0.65 • VDD where VDD is 1.8V ± 0.15V.
However, the LVTTL translator is supplied by a 2.5V nominal supply on this part. To ensure compliance with the specification, the translator was designed to accept the calculated
worst case value ( VIH = 0.65 • [1.8 - 0.15V]) rather than reference against a nominal 1.8V supply.
11. This value is the worst case maximum VIL over the specification range of the 1.8V power supply. The 1.8V LVTTL specification is VIL = 0.35 • VDD where VDD is 1.8V ± 0.15V.
However, the LVTTL translator is supplied by a 2.5V nominal supply on this part. To ensure compliance with the specification, the translator was designed to accept the calculated
worst case value ( VIL = 0.35 • [1.8 + 0.15V]) rather than reference against a nominal 1.8V supply.
12. For differential mode (RxS = LOW), A and A/VREF must be at the opposite rail.

NOTES:
1. Skew measured between all outputs or output pairs under identical input and output interfaces, transitions and load conditions on any one device. For single ended and differential
LVTTL outputs, this measurement is made when each output voltage passes through VDDQ/2. For differential LVTTL outputs, the true outputs are compared only with other true
outputs and the complementary outputs are compared only with other complementary outputs. For differential HSTL outputs, the measurement takes place at the crossing point
of the true and complementary signals.
2. For operating with either 1.8V or 2.5V LVTTL output interfaces with both true and complementary outputs enabled. Inverting skew is the skew between true and complementary
outputs switching in opposite directions under identical input and output interfaces, transitions and load conditions on any one device.
3. Skew measured is the difference between propagation delay times tPHL and tPLH of any output or output pair under identical input and output interfaces, transitions and load conditions
on any one device. For single ended and differential LVTTL outputs, this measurement is made when each output voltage passes through VDDQ/2. The measurement applies
to both true and complementary signals. For differential HSTL outputs, the measurement takes place at the crossing point of the true and complementary signals.
4. Skew measured is the magnitude of the difference in propagation times between any outputs or output pairs of two devices, given identical transitions and load conditions at identical
VDD/VDDQ levels and temperature.
5. Guaranteed by design.

NOTES:
1. For differential input mode, RxS is tied to GND.
2. Both differential input signals should not be driven to the same level simultaneously. The input will not change state until the inputs have crossed and the voltage range defined
by VDIF has been met or exceeded.
3. Differential mode only. VDIF specifies the minimum input voltage (VTR - VCP) required for switching where VTR is the "true" input level and VCP is the "complement" input level.
The AC differential voltage must be achieved to guarantee switching to a new state.
4. For single-ended operation, A/VREF is tied to DC voltage (VREF). Refer to each input interface's DC specification for the correct VREF range.
5. Voltage required to switch to a logic HIGH, single-ended operation only.
6. Voltage required to switch to a logic LOW, single-ended operation only.

1.8V or 2.5V LVTTL Output Propagation and Skew Waveforms
NOTES:
1. For the HSTL and eHSTL outputs, tPHL and tPLH are measured from the input passing through VTHI or input pair crossing to the crossing point of each Qn and Qn.
2. For 1.8V and 2.5V LVTTL outputs, tPHL and tPLH are measured from the input passing through VTHI or input pair crossing to the slower of Qn or Qn passing through VTHO.
3. Pulse skew is calculated using the following expression:
tSK(P) = | tPHL - tPLH |
where tPHL and tPLH are measured on the controlled edges of any one output from the rising and falling edges of a single pulse. Note that the tPHL and tPLH shown above are
not valid measurements for this calculation because they are not taken from the same pulse.
