IDT5T9306
FEATURES:
• Guaranteed Low Skew < 25ps (max)
• Very low duty cycle distortion < 125ps (max)
• High speed propagation delay < 1.75ns (max)
• Additive phase jitter, RMS 0.159ps (typical) @ 125MHz
• Up to 1GHz operation
• Selectable inputs
• Hot insertable and over-voltage tolerant inputs
• 3.3V / 2.5V LVTTL, HSTL, eHSTL, LVEPECL (2.5V), LVPECL (3.3V),
CML, or LVDS input interface
• Selectable differential inputs to six LVDS outputs
• Power-down mode
• 2.5V VDD
• Available in VFQFPN package
DESCRIPTION:
TheIDT5T93062.5Vdifferential clockbufferisauser-selectabledifferential
inputtosixLVDSoutputs. ThefanoutfromadifferentialinputtosixLVDSoutputs
reduces loading on the preceding driver and provides an efficient clock
distributionnetwork. TheIDT5T9306canactasatranslatorfromadifferential
HSTL, eHSTL, LVEPECL (2.5V), LVPECL (3.3V), CML, or LVDS input to
LVDS outputs. A single-ended 3.3V / 2.5V LVTTL input can also be used to
translate to LVDS outputs. The redundant input capability allows for an
asynchronous change-over from a primary clock source to a secondary clock
source. Selectable reference inputs are controlled by SEL.
The IDT5T9306 outputs can be asynchronously enabled/disabled. When
disabled,theoutputswilldrivetothevalueselectedbytheGLpin. Multiplepower
and grounds reduce noise.

NOTES:
1. The 1V 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 750mV 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 2V/ns or greater is to be maintained in the 20% to 80% range of the input waveform.
