FEATURES
APPLICATIONS
All SONET and All GigE clock distribution
Fibre Channel clock and data distribution
Backplanes
Data distribution: OC-48, OC-48+FEC, XAUI
High-end, low-skew, multiprocessor synchronous
clock distribution
The SY58013U is a 2.5V/3.3V precision, high-speed, fully
differential 1:2 LVPECL fanout buffer. Optimized to provide
two identical output copies with less than 15ps of skew and
only 55fsRMS phase jitter, the SY58013U can process clock
signals as fast as 6GHz or data patterns up to 10.7Gbps.
The differential input includes Micrel’s unique, 3-pin input
termination architecture that interfaces to LVPECL, LVDS,
and CML differential signals, (AC- or DC-coupled) as small
as 100mV without any level-shifting or termination resistor
networks in the signal path. For AC-coupled input interface
applications, an on-board output reference voltage (VREF-
AC) is provided to bias the VT pin. The outputs are 400mV
LVPECL compatible, with extremely fast rise/fall times
guaranteed to be less than 80ps.
The SY58013U operates from a 2.5V ±5% supply or
3.3V ±10% supply and is guaranteed over the full industrial
temperature range (–40°C to +85°C). For applications that
require greater output swing or CML compatible outputs,
consider the SY58012U 1:2 fanout buffer with 800mV
LVPECL outputs, or the SY58011U 1:2 fanout buffer with
400mV CML outputs. The SY58013U is part of Micrel’s
high-speed, Precision Edge® product line. Datasheets and
support documentation can be found on Micrel’s web site at

Figure 4. Parallel Termination–Thevenin Equivalent
Note 1. For +2.5V systems: R1 = 250 ohms, R2 = 62.5 ohms
Note 2. For +3.3V systems: R1 = 130 ohms, R2 = 82 ohms
Figure 5. Three-Resistor “Y–Termination”
Note 1. Power-saving alternative to Thevenin termination.
Note 2. Place termination resistors as close to destination inputs as
possible.
Note 3. Rb resistor sets the DC bias voltage, equal to V
T.
For +2.5V systems Rb = 39 ohms.
For +3.3V systems Rb = 46 ohms to 50 ohms.
Note 4. C1 is an optional bypass capacitor intended to compensate for
any tr/tf mismatches.
OUTPUT TERMINATION RECOMMENDATIONS
LVPECL outputs have very low output impedance (open
emitter), and small signal swing which results in low EMI
(electro-magnetic interference). The LVPECL is ideal for
driving 50 ohms and 100 ohms controlled impedance
transmission lines. In addition, LVPECL is compatible for
driving standard PECL inputs since PECL inputs require only
100mV input swing. Further, there are several techniques
in terminating the LVPECL outputs, as shown in Figure 4
through 6.
Figure 6. Terminating Unused I/O
Note 1. Unused output (/Q) must be terminated to balance the output.
Note 2. For +2.5V systems: R1 = 250 ohms, R2 = 62.5 ohms, R3 = 1.25k ohms,
R4 = 1.2k ohms.
For +3.3V systems: R1 = 130 ohms, R2 = 82 ohms, R3 = 1k ohms,
R4 = 1.6k ohms.
Note 3. Unusedoutputpairs(Qand/Q)maybeleftoating.
