SY89312V
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 asynchronous and is asserted when it is high.
