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

■ Available in 16-pin (3mm x 3mm) QFN package

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

Note 1. Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not

implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings condi-

tions for extended periods may affect device reliability.

Note 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.

Note 3. Thermal performance assumes exposed pad is soldered (or equivalent) to the device’s most negative potential on the PCB.

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

Figure 4. Parallel Termination–Thevenin Equivalent

Note 1. Unused output (/Q) must be terminated to balance the output.

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

Note 2. For+2.5Vsystems: R1=250ohms,R2=62.5ohms,R3=1.25kohms,

R4 = 1.2k ohms.

For +3.3V systems: R1 = 130 ohms, R2 = 82 ohms, R3 = 1k ohms,

R4 = 1.6k

ohms.

Note 3.ꢀ Unusedꢀoutputꢀpairsꢀ(Qꢀandꢀ/Q)ꢀmayꢀbeꢀleftꢀﬂoating.

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. R resistor sets the DC bias voltage, equal to V .

For +2.5V systems R = 39 ohms.

For +3.3V systems R = 46 ohms to 50 ohms.

Note 4. C1 is an optional bypass capacitor intended to compensate for

any t /t mismatches.
