MC100EL90
−3.3V / −5VTriple 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 VEE 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 VCC supply should be connected to the positive supply, and
the VEE pin should be connected to the negative power supply. The
GND pins, as expected, are connected to the system ground plane.
Both VEE and VCC should be bypassed to ground via 0.01 mF
capacitors.
Under open input conditions, the D input will be biased at VEE/2 and
the D input will be pulled to VEE. This condition will force the Q
output to a LOW, ensuring stability.
The VBB pin, an internally generated voltage supply, is available to
this device only. For single-ended input conditions, the unused
differential input is connected to VBB as a switching reference voltage.
VBB may also rebias AC coupled inputs. When used, decouple VBB
and VCC via a 0.01 mF capacitor and limit current sourcing or sinking
to 0.5 mA. When not used, VBB should be left open.
