DESCRIPTION
The SY10/100E116 are quint differential line receivers
designed for use in new, high-performance ECL systems.
These devices have emitter-follower outputs and an
internally generated reference supply (VBB) for single-
ended reception.
Active current sources combined with Micrel’s ASSET™
technology provide the receivers with excellent common
mode noise rejection.
The receiver design features clamp circuitry to cause a
defined output state if both the inverting and non-inverting
inputs are left open; in this case the Q output goes LOW,
while the Q output goes HIGH.
If both inverting and non-inverting inputs are at equal
potential, the receiver does not go to a defined state, but
rather shares current in normal differential amplifier fashion,
producing output voltage levels midway between HIGH
and LOW.
The VBB output is intended for use as a reference
voltage for single-ended reception of ECL signals to that
device only. When using VBB for this purpose, it is
recommended that VBB is decoupled to VCC via a 0.01 µF
capacitor.
For higher bandwidth, please refer to the SY10/100E416
device.
