Datasheet
The MAX3620 series is a family of high-performance
passive delay lines for use in QDR/QDRII synchronous
memory systems. These delay lines support high-speed
transceiver logic (HSTL) source terminated transmission
with an unterminated load at the receiver, and deliver
accurate delays of 0.75ns, 1.00ns, 1.25ns, and 1.50ns
for the generation of the quarter clock phase. The
MAX3620 is offered in a small 3mm x 3mm package
which contains two delay lines of equal length that can
be driven either differentially or single-endedly.
19-3550; Rev 0; 1/05
