FEATURES

APPLICATIONS

Selects between 1 of 8 inputs, and provides two

precision, low skew CML output copies

Guaranteed AC performance over temperature and

voltage:

• DC to 5Gbps throughput

• <450ps propagation delay IN-to-Q (V

• <70ps t

• <15ps skew (output-to-output)

Unique, patent-pending, channel-to-channel

isolation design provides superior crosstalk

performance

Ultra-low jitter design:

• <1ps

• <10ps

• <0.7ps

Unique, patent-pending, input termination and VT

pin accepts DC- and AC-coupled inputs (CML, PECL,

LVDS)

400mV CML output swing

50 source terminated outputs minimize round-trip

reflections

Power supply 2.5V 5% or 3.3V 10%

–40 C to +85 C temperature range

Available in 44-pin (7mm x 7mm) MLF

ULTRA PRECISION 8:1 MUX

WITH INTERNAL TERMINATION

AND 1:2 CML FANOUT BUFFER

300mV)

multiplexer with a 1:2 differential fanout buffer optimized for

precision telecom and enterprise server distribution

applications. The SY58037U distributes clock frequencies

from DC to 4GHz and data rates to 5Gpbs guaranteed over

temperature and voltage.

3-pin input termination architecture that directly interfaces

to any differential signal (AC- or DC-coupled) as small as

100mV (200mVpp) without any level shifting or termination

resistor networks in the signal path. The outputs are 50

source-terminated CML with extremely fast rise/fall time

guaranteed to be less than 70ps.

that significantly improves channel-to-channel crosstalk

performance.
