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 (V
ended reception.
Active current sources combined with Micrel-Synergy’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.

NOTES:
1. VPP is the minimum differential input voltage required to assure full ECL levels are present at the outputs.
2. VCMR is referenced to the most positive side of the differential input signal. Normal operation is obtained when the "HIGH" input is within the VCMR range
and the input swing is greater than VPP (min.) and <1V.

NOTES:
1. Minimum input swing for which AC parameters are guaranteed.
2. Within-device skew is defined as identical transitions on similar paths through a device.
3. Duty cycle skew is defined only for differential operation when the delays are measured from the cross point of the inputs to the cross point of the
outputs.
