General Description
The SY89297U is a DC-3.2Gbps programmable,
two-channel delay line. Each channel has a delay
range from 2ns to 7ns (5ns delta delay) in
programmable increments as small as 5ps. The delay
step is extremely linear and monotonic over the entire
programming range, with 15ps INL over temperature
and voltage.
The delay varies in discrete steps based on a serial
control word provided by the 3-pin serial control
(SDATA, SCLK, and SLOAD). The control word for
each channel is 10-bits. Both channels are
programmed through a common serial interface. For
increased delay, multiple SY89297U delay lines can be
cascaded together.
The SY89297U provides two independent 3.2Gbps
delay lines in an ultra-small 4mm x 4mm, 24-pin QFN
package. For other delay line solutions, consider the
SY89295U and SY89296U single-channel delay lines.
Evaluation boards are available for all these parts.
