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.
