The SY100EL16VO is a differential receiver amplifier
optimized for crystal oscillator applications. The device includes
an additional low gain (+10V/V) output stage (Q
FB
) ideal for
feedback applications common in crystal oscillator gain blocks.
The SY100EL16VO is fully differential, with a bandwidth
> 800MHz over temperature and voltage. For applications that
require output disable control, an Enable pin (/EN) will force
the differential output into a fixed logic state. The
SY100EL16VO also includes a V
BB
reference voltage for
single-ended or AC-coupled applications.
The SY100EL16VO PECL logic is 100k ECL compatible.
Operation is guaranteed over the –40°C to +85°C temperature
range and 3.3V to 5V nominal supply voltage range.

Function
Differential clock outputs for feedback path:
Nominal DC gain +10.
PECL, LVPECL, ECL, LVECL differential inputs:
Internal 75kΩ pull-down resistor.
V
CC
–1.32V reference voltage for single-ended
inputs: It provides the switching reference for the
input differential amplifier. When unused, it can be
left open. For single-ended PECL applications
connect V
BB
to /D input, and bypass with a 0.01µF
capacitor to V
CC
.
Enable: PECL compatible input control with internal
75kΩ pull-down resistor. It controls the high-gain
output (Q
HG
). When HIGH, Q
HG
is low and /Q
HG
is
high. /EN is synchronous so that the outputs will only
be enabled/disabled when they are in the LOW state.
Negative power supply: For ECL/LVECL operation,
connect to negative supply. For PECL/ LVPECL
operation, connect to GND.
