The SY100EL16VO is a differential receiver amplifier
optimized for crystal oscillator applications. The device includes
an additional low gain (+10V/V) output stage (QFB) 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 VBB 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.
• < 200ps differential propagation delay (D to QFB)
• < 730ps differential propagation delay (D to QHG)
• < 250ps tr / tf

VBB
VCC –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 VBB to /D input, and bypass with a 0.01µF
capacitor to VCC.
/EN
Enable: PECL compatible input control with internal
75kΩ pull-down resistor. It controls the high-gain
output (QHG). When HIGH, QHG is low and /QHG is
high. /EN is synchronous so that the outputs will only
be enabled/disabled when they are in the LOW state.
VEE
Negative power supply: For ECL/LVECL operation,
connect to negative supply. For PECL/ LVPECL
operation, connect to GND.
