January 2001 CLC001 Serial Digital Cable Driver with Adjustable Outputs General Description Key Specifications The CLC001 is a monolithic, high-speed cable driver designed for use in SMPTE 259M serial digital video and ITU-T G.703 serial digital data transmission applications. The CLC001 drives 75 transmission lines (Belden 8281 or equivalent) at data rates up to 622 Mbps. Controlled output rise and fall times (400 ps typical) minimize transitioninduced jitter. The output voltage swing is adjustable from 800mVp-p to 1Vp-p using an external resistor. The CLC001's output stage consumes less power than other designs. The differential inputs accept LVDS signal levels, LVPECL levels directly or PECL with attenuation networks. All these make the CLC001 an excellent general purpose high speed driver for high-speed, long distance data transmission applications. The CLC001 is powered from a single +3.3V supply and comes in a small 8-pin SOIC package. n n n n 400 ps rise and fall times Data rates to 622 Mbps 100 mV differential input threshold Low residual jitter Features n n n n n Adjustable output amplitude Differential input and output Accepts LVPECL or LVDS input swings Low power dissipation Single +3.3V supply Applications Digital routers and distribution amplifiers Coaxial cable driver for digital transmission lines Twisted pair driver Serial digital video interfaces for the commercial and broadcast industry n SMPTE, Sonet/SDH, and ATM compatible driver n Buffer applications n n n n Typical Application DS101329-1 Connection Diagram (8-Pin SOIC) DS101329-2 Order Number CLC001AJE See NS Package Number M08A (c) 2001 National Semiconductor Corporation DS101329 www.national.com CLC001 Serial Digital Cable Driver with Adjustable Outputs PRELIMINARY CLC001 Absolute Maximum Ratings (Note 1) ESD Rating (HBM) Package Thermal Resistance JA Surface Mount AJE JC Surface Mount AJE Reliability Information Transistor count If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications.

They are not meant to imply that the devices should be operated at these limits. The table of "Electrical Characteristics" specifies conditions of device operation. Note 2: Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are stated referenced to VSS = 0V. Note 3: Typical values are at 25C and 3.3V. Note 4: Spec is guaranteed by design. Note 5: RL = 75, AC Coupled at 270 Mbps, RREF = 1.91k 1% (for 800mVp-p 10%). Note 6: The VBB output is intended as a bias supply pin for the inputs of this device only. It is not designed as a power supply output and should not be used to power other devices. Note 7: RL = 75, AC Coupled at 622 Mbps, RREF = 1.5k 1% (for 1Vp-p 10%). Note 8: Input Current Balance (IINB) is the difference between the Input Current (IIN) on VIN+ and VIN- for the same bias condition. Test Loads DS101329-4 FIGURE 1.

PCB Layout Recommendations Printed circuit board layout affects the performance of the CLC001. 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 F monolithic ceramic capacitor in parallel with a 6.8 F tantalum electrolytic capacitor located no more than 0.1 (2.5 mm) from the device power pins. 7 www.national.com CLC001 Device Operation CLC001 Serial Digital Cable Driver with Adjustable Outputs Physical Dimensions inches (millimeters) unless otherwise noted Order Number CLC001AJE NS Package Number M08A LIFE SUPPORT POLICY NATIONAL'S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION.
