DESCRIPTION

•
Texas Instruments' Comlinear CLC006 is a
monolithic, high-speed cable driver designed for the
SMPTE 259M serial digital video data transmission
standard. The CLC006 drives 75Ω transmission lines
(Belden 8281 or equivalent) at data rates up to 400
Mbps. Controlled output rise and fall times (650 ps
typical) minimize transition-induced jitter. The output
voltage swing, typically 1.65V, set by an accurate,
low-drift internal bandgap reference, delivers an 800
mV swing to back-matched and terminated 75Ω
cable. Output swing is adjustable from 0.7 VP-P to 2
VP-P using external resistors.

Buffer Applications
The CLC006’s class AB output stage consumes less
power than other designs, 185 mW with both outputs
terminated, and requires no external bias resistors.
The differential inputs accept a wide range of digital
signals from 200 mVP-P to ECL levels within the
specified common-mode limits. All this make the
CLC006 an excellent general purpose high speed
driver for digital applications.
The CLC006 is powered from a single +5V or −5.2V
supply and comes in an 8-pin SOIC package.

Operation
INPUT INTERFACING
The CLC006 has high impedance, emitter-follower buffered, differential inputs. Single-ended signals may also be
input. Transmission lines supplying input signals must be properly terminated close to the CLC006. Either A.C. or
D.C. coupling as in Figure 4 or Figure 5 may be used. Figure 4, Figure 6 and Figure 7 show how Theveninequivalent resistor networks are used to provide input termination and biasing. The input D.C. common-mode
voltage range is 0.8V to 2.5V below the positive power supply (VCC). Input signals plus bias should be kept within
the specified common-mode range. For an 800 mVP-P input signal, typical input bias levels range from 1.2V to
2.1V below the positive supply.

OUTPUT INTERFACING
The CLC006’s class AB output stage, Figure 8, requires no standing current in the output transistors and
therefore requires no biasing or pull-down resistors. Advantages of this arrangement are lower power dissipation
and fewer external components. The output may be either D.C. or A.C. coupled to the load. A bandgap voltage
reference sets output voltage levels which are compatible with F100K and 10K ECL when correctly terminated.
The outputs do not have the same output voltage temperature coefficient as 10K. Therefore, noise margins will
be reduced over the full temperature range when driving 10K ECL. Noise margins will not be affected when
interfacing to F100K since F100K is fully voltage and temperature compensated.

OUTPUT AMPLITUDE ADJUSTMENT
The high and low output levels of the CLC006 are set by a circuit shown simplified in Figure 10. Output high and
low levels may be set independently with external resistor networks connected between REXT-H (pin 3), REXT-L (pin
4) and the power supplies. The resistor networks affect the high and low output levels by changing the internally
generated bias voltages, VH and VL. The nominal high and low output levels are VCC−1.7V and VCC−3.3V,
respectively, when the pins REXT-H and REXT-L are left unconnected. Though the internal components which
determine output voltage levels have accurate ratios, their absolute values may be controlled only within about
±15% of nominal. Even so, without external adjustment, output voltages are well controlled. A final design should
accommodate the variation in externally set output voltages due to the CLC006’s part-to-part and external
component tolerances.
Output voltage swing may be reduced with the circuit shown in Figure 11. A single resistance chosen with the aid
of the graph, Figure 12, is connected between pins 3 and 4. Output voltage swing may be increased with the
circuit of Figure 13. Figure 14 is used to estimate a value for resistor R. Note that both of these circuits and the
accompanying graphs assume that the CLC006 is loaded with the standard 150Ω. Be aware that output loading
will affect the output swing and the high and low levels. It may be necessary to empirically select resistances
used to set output levels when the D.C. loading on the CLC006 differs appreciably from 150Ω.

OUTPUT RISE AND FALL TIMES
Output load capacitance can significantly affect output rise and fall times. The effect of load capacitance, stray or
otherwise, may be reduced by placing the output back-match resistor close to the output pin and by minimizing
all interconnecting trace lengths. Figure 15 shows the effect on risetime of parallel load capacitance across a
150Ω load.

PCB Layout Recommendations
Printed circuit board layout affects the performance of the CLC006. The following guidelines will aid in achieving
satisfactory device performance.
• Use a ground plane or power/ground plane sandwich design for optimum performance.
• Bypass device power with a 0.01 µF monolithic ceramic capacitor in parallel with a 6.8 µF tantalum
electrolytic capacitor located no more than 0.1” (2.5 mm) from the device power pins.
• Provide short, symmetrical ground return paths for:
– inputs,
– supply bypass capacitors and
– the output load.
• Provide short, grounded guard traces located
– under the centerline of the package,
– 0.1” (2.5 mm) from the package pins
– on both top and bottom of the board with connecting vias.
