EEPROM PROGRAMMABLE 2.5V ZERO DELAY PLL DIFFERENTIAL CLOCK DRIVER
SINGLE-ENDED INPUT AC TEST CONDITIONS FOR 2.5V LVTTL
Symbol Parameter Value Units
VIH Input HIGH Voltage VDD V
VIL Input LOW Voltage 0V
VTHI Input Timing Measurement Reference Level
(1)
VDD/2 V
tR, tF Input Signal Edge Rate
(2)
2 V/ns
NOTES:
1. A nominal 1.25V timing measurement reference level is specified to allow constant, repeatable results in an automatic test equipment (ATE) environment.
2. The input signal edge rate of 2V/ns or greater is to be maintained in the 10% to 90% range of the input waveform.

NOTES:
1. A nominal 2.5V 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 nominal 1.25V 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 2.5V/ns or greater is to be maintained in the 20% to 80% range of the input waveform.
NOTES:
1. These power consumption characteristics are for all the valid input interfaces and cover the worst case input and output interface combinations.
2. The termination resistors are excluded from these measurements.
3. If the differential input interface is used, the true input is held LOW and the complementary input is held HIGH.
4. Bit 60 = 1.
5. All outputs are at the same interface level.
