DESCRIPTION
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 mon 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 patible. Operation is guaranteed over the
- 40°C to +85°C temperature range and 3.3V to 5V nominal supply voltage range.
