7. Power Consumption
Fairchild Semiconductor
7.1 Power for LVPECL I/O
Chip power, consists of three integral elements (refer to Figure 16):
1. Input Power—This element has two components:
2. Core Power—This element is the same for LVPECL or LVDS outputs. Core power is a function of
3. Output Power—This element is a fixed amount for each differential output. The value is zero if the
(320mW + 10mW/Input)
data rate (Mb/s) and the number of connection paths through the switch matrix.
Output Enable (OE#) is disabled or set to OFF.
Example: Worst Case = (320mW + 800mW) + (0.015 mW x 1600 x 80) + (37mW x 80)

a steady state component that is always ON, and
a component that is based on the number of inputs being used.
