DATA SHEET
FEATURES: DESCRIPTION:
Guaranteed Low Skew < 40ps (max) The IDT5T9306 2.5V differential clock buffer is a user-selectable
Very low duty cycle distortion < 125ps (max) differential input to six LVDS outputs. The fanout from a differential input
High speed propagation delay < 1.75ns (max) to six LVDS outputs reduces loading on the preceding driver and provides
Additive phase jitter, RMS 0.159ps (typical) @ 125MHz an efficient clock distribution network. The IDT5T9306 can act as a
Up to 1GHz operation translator from a differential HSTL, eHSTL, LVEPECL (2.5V), LVPECL
Selectable inputs (3.3V), CML, or LVDS input to LVDS outputs. A single-ended 3.3V / 2.5V
Hot insertable and over-voltage tolerant inputs LVTTL input can also be used to translate to LVDS outputs. The redundant
3.3V / 2.5V LVTTL, HSTL, eHSTL, LVEPECL (2.5V), LVPECL input capability allows for an asynchronous change-over from a primary
(3.3V), CML, or LVDS input interface clock source to a secondary clock source. Selectable reference inputs are
Selectable differential inputs to six LVDS outputs controlled by SEL.
Power-down mode The IDT5T9306 outputs can be asynchronously enabled/disabled. When
2.5V VDD disabled, the outputs will drive to the value selected by the GL pin. Multiple
Available in VFQFPN package power and grounds reduce noise.
