0V to 3.
8V power supply option s Guaranteed AC parameters over temperature: • fMAX = 800MHz • < 200ps differential propagation delay (D to QFB) • < 730ps differential propagation delay (D to QHG) • < 250ps tr / tf s Low-gain feedback path QFB = +10V/V s VBB reference output voltage s Wide temperature range: –40°C to +85°C s Available in 10-pin (3mm × 3mm) MSOP s LVPECL/LVECL/CMOS compatible EN option Precision Edge® DESCRIPTION The SY89207L is a differential receiver amplifier optimized for crystal oscillator applications.
The device includes an additional low differential gain (+10V/V) output stage (QFB) ideal for feedback applications common in crystal oscillator gain blocks.
The SY89207L is fully differential, with a bandwidth > 800MHz over temperature and voltage.
For applications that require output disable control, a LVPECL/LVECL/CMOS compatible enable pin (EN) will force the differential output into a fixed logic state.
The SY89207L also includes a VBB reference voltage for single-ended or AC-coupled applications.
The SY89207L PECL logic is 100k ECL compatible.
Operation is guaranteed over the –40°C to +85°C temperature range and 3.
3V nominal supply voltage range.
