MC100EL90
−3.3V / −5V Triple ECL Input
to PECL Output Translator
Description
The MC100EL90 is a triple ECL to PECL translator. The device
receives either −3.3 V or −5 V differential ECL signals, determined by
the V_EE supply level, and translates them to standard +5 V differential
PECL output signals.
To accomplish the level translation, the EL90 requires three power
rails. The V_CC supply should be connected to the positive supply, and
the V_EE pin should be connected to the negative power supply. The
GND pins, as expected, are connected to the system ground plane.
Both V_EE and V_CC should be bypassed to ground via 0.01 mF
capacitors.
Under open input conditions, the D input will be biased at V_EE/2 and
the D input will be pulled to V_EE. This condition will force the Q
output to a LOW, ensuring stability.
The V_BB pin, an internally generated voltage supply, is available to
this device only. For single-ended input conditions, the unused
differential input is connected to V_BB as a switching reference voltage.
V_BB may also rebias AC coupled inputs. When used, decouple V_BB
and V_CC via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, V_BB should be left open.
