PIN NAMES
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.
