1. Electrical Characteristics (Key Values & Context)


️· Supply Voltages: (Based on a brief search within the document, I could not find definitive supply voltage ranges. Look for parameters related to `VCC`, `VEE` within the detailed electrical specifications.)
️· Input Voltages:
- VIL (Low-Level Input Voltage): Values are referenced but specific numeric values need to be found in the full table of electrical characteristics.
- VIH (High-Level Input Voltage): Similar to VIL, requires referencing the full table.
️· Output Characteristics: The document discusses output signal swings and characteristics. Specific values for output voltage levels are dependent on the chosen signalling mode (LVPECL or HSTL). Look for parameters related to `VOUT`.
️· Jitter Performance: A major focus of the datasheet. See section 13 for more details.

2. Timing Characteristics (Key Values & Context)

️· VTT (Reference Voltage): Referenced, requires finding within the full timing parameters table.
️· VCM (Common-Mode Input Voltage): Referenced, needs numerical value from the datasheet.
️· Output Rise/Fall Time (tr, tf): 0.08 ns – 0.3 ns (referenced within Figure 2)
️· Propagation Delay (tPD): Figure 4 shows "Propagation Delay" along with other skew parameters. Specific values require referencing the figure and associated table.
️· Output-to-Output Skew (tSK(O)): Referenced in Figure 4. Requires finding values in the datasheet.
️· Output Pulse Skew (|tPLH – tPHL|): Referenced in Figure 4. Requires finding values in the datasheet.

3. Jitter Specifications (Key Values & Context)

This is a critical section for high-speed clock distribution chips.
