MICROCHIP SY89297UMH

The SY89297U is a DC - 3.2 Gbps programmable, two - channel delay line. Each channel has a delay range from 2 ns to 7 ns (5 ns delta delay) in programmable increments as small as 5 ps. The delay step is extremely linear and monotonic over the entire programming range, with 15 ps 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 3.2 Gbps delay lines in an ultra - small 4 mm×4 mm, 24 - pin QFN package.
