† Voltages are with respect to ground unless otherwise stated.
‡ Typical figures are for design aid only: not guaranteed and not subject to production testing.
Supply voltage and operating temperature are as per Recommended Operating Conditions.
Note 1: The I
LVPECL
current is determined by the external termination network connected to LVPECL outputs. More than 25% of this
current (10 mA) flows outside the chip and it does not contribute to the internal power dissipation. The Supply Current value
listed in the table includes this current to reflect total current consumption of the ZL30415 and the attached LVPECL
termination network.
Note 2: LVPECL outputs terminated with Z
T
= 50 Ω resistors biased to V
CC
-2V (see Figure 9).
