(1) See applications section Section 8.1 for definition of V_ID and V_OD voltages.

(2) For Icc for specific part configuration, see applications section Section 11.1 for calculating Icc.

(3) The minimum recommended slew rate for all input clocks is 0.5 V/ns. This is especially true for single-ended clocks. Phase noise performance will begin to degrade as the clock input slew rate is reduced. However, the device will function at slew rates down to the minimum listed. When compared to single-ended clocks, differential clocks (LVDS, LVPECL) will be less susceptible to degradation in phase noise performance at lower slew rates due to their common mode noise rejection. However, it is also recommended to use the highest possible slew rate for differential clocks to achieve optimal phase noise performance at the device outputs.

(4) Equal loading and identical clock output configuration on each clock output is required for specification to be valid. Specification not valid for delay mode.

(5) Ensured by characterization.

(6) Refer to typical performance charts for output operation performance at higher frequencies than the minimum maximum output frequency.

(7) For LCPECL, the common mode voltage is regulated (VOH=1.6V, VOL=VOH-Vsw, Vcm=(VOH+VOL)/2 ) and is more stable against with PVT (process, supply, temperature) variations than conventional LVPECL implementations..

(8) With proper selection of external emitter resistors, LCPECL can also be used for DC-coupling with devices with low common voltage such as 0.5V or 0.8V etc.

(9) Refer to application note AN-912 Common Data Transmission Parameters and their Definitions (SNLA036) for more information.
