Micrel : Delay line IC is very linear and monotonic

Micrel Inc. has launched the dual channel SY89297U delay line IC. The second generation device can be serially programmed to provide just 5ns of delay per channel while running up to 3.2Gbps/1.6GHz. The delay is very linear and monotonic, providing precise delay for high-speed applications. The IC is currently available in volume with pricing starting at $9.23 for 1K quantities. In addition, samples can now be ordered directly from the Micrel website at:

“The programmable delay feature of the SY89297U makes design work simpler for these complex and faster than ever high-speed applications,” said Thomas S. Wong, vice president High Bandwidth products, Micrel. “Fast linear delays coupled with 5ps/step resolution provide a precise delayed signal while the IC’s ferociously high speeds and low power makes this part ideal for today’s economical designs.”

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 0ºC to +75ºC and supply voltage of 2.5V ±5 percent. The patented 3-pin internal termination input allows use of the part with any differential (PECL, CML, or LVDS) signals. The device is offered in MLF™ packaging, which features low inductance and capacitance.
