SY89312V
SY89312V is PECL/ECL CLOCK GENERATOR manufactured by Micrel Semiconductor.
3.3V/5V, 4GHz PECL/ECL ÷2 Clock Generator Precision Edge®
General Description
The SY89312V is an integrated ÷2 divider with differential clock inputs. It is functionally equivalent to the SY100EP32V but in an ultra-small 8-pin QFN package that Features a 70% smaller footprint.
The VBB pin, an internally generated voltage supply, is available for this device only. For single-ended input conditions, the unused differential input is connected to VBB as a switching reference voltage. VBB can also bias ACcoupled inputs. When used, decouple VBB and VCC via a 0.01µF capacitor and limit current sourcing or sinking to 0.5mA. When not in use, VBB should be left open.
The reset pin is...
