Definition
Input ECL. Similar to 100 K ECL, but with pull-down. Thus if the input is left
unconnected, the buffer generates a default value of “0”. The input can also be directly
connected to ground to generate a “1”.
Output ECL. Similar to 100 K ECL but should be terminated with RTT ≥ 300 Ω, and do
not exceed 10cm connection distance.
50 matched output driver. Will drive AC coupled 50 Ω loads, with 150 Ω pull-up
resistors for broad band matching. All unused outputs should have 150 Ω pull-up
resistors, and AC coupled to a 50 Ω resistor to ground.
Input with internal 50 Ω terminations. Input is diode level shifted so that it can swing
around ground. Can be driven with single-end configuration. Commonly used with input
single-end AC coupling from an O-BLL driver or another 50 Ω source, or differential
direct coupling from an O-BLL driver.
Filter capacitor node.
Power supply or ground.
