(6) The junction-to-board characterization parameter, ΨJB estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining RθJA , using a procedure described in JESD51-2a (sections 6 and 7). (7) The junction-to-case(bottom) thermal resistance is obtained by simulating a cold plate test on the exposed (power) pad. No specific JEDEC standard test exists, but a close description can be found in the ANSI SEMI standard G30-88. 7.5 Electrical Characteristics (3.15 V < VCC < 3.45 V, –40 °C < TA < 85 °C and TPCB ≤ 105 °C. Typical values at VCC = 3.3 V, TA = 25 °C, at the Recommended Operating Conditions and are not assured.)

(2) In order to meet the jitter performance listed in the subsequent sections of this data sheet, 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. (3) See Differential Voltage Measurement Terminology for definition of VID and VOD voltages. (4) Assured by characterization.
