ULTRA-PRECISION
DIFFERENTIAL CML 2:1 MUX with
INTERNAL I/O TERMINATION
Precision Edge™
Precision ESdYg5e8™017U
SY58017U
FEATURES
s Guaranteed AC performance over temperature and
voltage:
• DC to > 10.7Gbps data throughput
Precision Edge™
• DC to > 7GHz fMAX (clock)
• < 240ps propagation delay
DESCRIPTION
• < 60ps tr / tf times
s Ultra-low crosstalk-induced jitter: < 0.7psrms
s Ultra-low jitter design:
• < 1psrms random jitter
• < 10psp-p deterministic jitter
• < 10psp-p total jitter (clock)
s Unique input termination and VT pin accepts DC-
coupled and AC-coupled inputs (CML, PECL, LVDS)
The SY58017U is a 2.5V/3.3V precision, high-speed, 2:1
differential MUX capable of handling clocks up to 7GHz
and data up to 10.7Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that allows customers to interface
to any differential signal (AC- or DC-coupled) as small as
100mV without any level shifting or termination resistor
networks in the signal path. The outputs are 50Ω source
s Internal 50Ω output source termination
terminated CML, with extremely fast rise/fall times
s Typical 400mV CML output swing (RL = 50Ω)
s Power supply 2.5V ±5% or 3.3V ±10%
s –40°C to +85°C temperature range
s Available in 16-pin (3mm × 3mm) MLF™ package
guaranteed to be less than 60ps.
The SY58017U operates from a 2.5V ±5% supply or a
3.3V ±10% supply and is guaranteed over the full industrial
temperature range of –40°C to +85°C. For applications that
require LVPECL outputs, consider the SY58018U or
SY58019U Multiplexers with LVPECL outputs. The

Notes:
9. High-frequency AC parameters are guaranteed by design and characterization.
10. Input-to-input skew is the difference in time from and input-to-output in comparison to any other input-to-output. In addition, the input-input skew does
not include the output skew.
11. Part-to-part skew is defined for two parts with identical power supply voltages at the same temperature and with no skew of the edges at the
respective inputs.
12. RJ is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps/3.2Gbps.
13. DJ is measured at 2.5Gbps/3.2Gbps, with both K28.5 and 223–1 PRBS pattern.
14. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, Tn–Tn–1 where T is the time between rising edges of the output
signal.
15. Total jitter definition: with an ideal clock input of frequency ≤ fMAX, no more than one output edge in 1012 output edges will deviate by more than the
specified peak-to-peak jitter value.
16. Crosstalk is measured at the output while applying two similar frequencies that are asynchronous with respect to each other at the inputs.
