SY100S815
FEATURES
■ Quad PECL version of popular ECLinPS E111
■ Low skew
®
Precision Edge
■ Guaranteed skew spec
DESCRIPTION
■ TTL enable input
The SY100S815 is a low skew 1-to-4 PECL differential
driver designed for clock distribution in new, high-
performance PECL systems. It accepts either a PECL
clock input or a TTL input by using the TTL enable pin TEN.
When the TTL enable pin is HIGH, the TTL input is enabled
and the PECL input is disabled. When the enable pin is set
LOW, the TTL input is disabled and the PECL input is
enabled.
■ Selectable TTL or PECL clock input
■ Single +5V supply
■ Differential internal design
■ PECL I/O fully compatible with industry standard
■ Internal 75kΩ PECL input pull-down resistors
■ Available in 16-pin SOIC package
The device is specifically designed and produced for low
skew. The interconnect scheme and metal layout are
carefully optimized for minimal gate-to-gate skew within
the device. Wafer characterization and process control
ensure consistent distribution of propagation delay from lot
to lot. Since the S815 shares a common set of “basic”
processing with the other members of the ECLinPS family,
wafer characterization at the point of device personalization
allows for tighter control of parameters, including
propagation delay.
To ensure that the skew specification is met, it is
necessary that both sides of the differential output are
terminated into 50Ω, even if only one side is being used. In
most applications, all nine differential pairs will be used
and, therefore, terminated. In the case where fewer than
nine pairs are used, it is necessary to terminate at least the
output pairs on the same package side (i.e. sharing the
same VCCO as the pair(s) being used on that side) in order
to maintain minimum skew.

Notes:
1. Part-to-part skew is defined as Max. — Min. value at the given temperature.
2. The differential propagation delay is defined as the delay from the crossing points of the differential input signals to the crossing point of the
differential output signals.
3. The single-ended propagation delay is defined as the delay from the 50% point of the input signal to the 50% point of the output signal.
4. The within-device skew is defined as the worst case difference between any two similar delay paths within a single device.
5. VPP (min.) is defined as the minimum input differential voltage which will cause no increase in the propagation delay. The VPP (min.) is AC limited for
the S815, as a differential input as low as 50mV will still produce full PECL levels at the output.
6. VCMR is defined as the range within which the VIH level may vary, with the device still meeting the propagation delay specification. The VIL level must
be such that the peak-to-peak voltage is less than 1.0V and greater than or equal to VPP (min.).
