Micrel is offering a dual channel delay line IC which can be serially programmed to provide just 5ns of delay per channel while running up to 3.2Gbit/s/1.6GHz. 

The device includes three-pin serial programming to adjust signal delays, making designs simple. Two channels provide more flexibility to the designer. 

The part is designed to provide 10ns of signal delay by using both channels. Multiple SY89297Us can be cascaded to generate even higher delay. 

The product operation is guaranteed over 0 to +75 deg C and supply voltage of 2.5V +/-5 per cent.

The patented 3-pin internal termination input allows use of the part with any differential (PECL, CML, or LVDS) signals.
