Two banks of five outputs each provide low-skew copies of CLK. After power up, the default state of the outputs is low regardless of the state of the control pins. For normal operation, the outputs of bank 1Y[0:4] or 2Y[0:4] can be placed in a low state when the control pins (1G or 2G, respectively) are held low and a negative clock edge is detected on the CLK input. The outputs of bank 1Y[0:4] or 2Y[0:4] can be switched into the buffer mode when the control pins (1G and 2G) are held high and a negative clock edge is detected on the CLK input. The device operates in a 2.5-V and 3.3-V environment. The built-in output enable glitch suppression ensures a synchronized output enable sequence to distribute full period clock signals. 1 • • • • High-Performance 1:10 Clock Driver Operates up to 200 MHz at VDD 3.3 V Pin-to-Pin Skew < 100 ps at VDD 3.3 V VDD Range: 2.3 V to 3.6 V Operating Temperature Range –40°C to 105°C Supports 105ºC Ambient Temperature (see Thermal Considerations) Output Enable Glitch Suppression Distributes One Clock Input to Two Banks of Five Outputs 25-Ω On-Chip Series Damping Resistors Packaged in 24-Pin TSSOP 2 Applications • The CDCVF2310 is characterized for operation from –40°C to 85°C.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The CDCVF2310 is a LVCMOS buffer solution that can operate up to 200 MHz. Low output skew as well as the ability for glitchless output enable and disable is featured to simultaneously enable or disable buffered clock outputs as necessary in the application. 9.2 Typical Application 100 MHZ LVCMOS Oscillator CLKIN VDD 50 W Trace Y0 CMOS CPU Clock Y1 CMOS FPGA Clock 100 W 1G 50 W Trace From CPU GND PLL Reference Yn 100 W Figure 7. Example System Configuration 9.2.1 Design Requirements The CDCVF2310 shown in Figure 7 is configured to fan out a 100-MHz signal from a local LVCMOS oscillator. The CPU is configured to control the output state through 1G. The configuration example is driving three LVCMOS receivers in a backplane application with the following properties: • The CPU clock can accept a full swing DC-coupled LVCMOS signal. A series resistor is placed near the CDCVF2310 to closely match the characteristic impedance of the trace to minimize reflections. • The FPGA clock is similarly DC-coupled with an appropriate series resistor placed near the CDCVF2310. • The PLL in this example can accept a lower amplitude signal, so a Thevenin's equivalent termination is used. The PLL receiver features internal biasing, so AC-coupling can be used when common-mode voltage is mismatched. 9.2.2 Detailed Design Procedure Refer to Electrical Characteristics table to determine the appropriate series resistance needed for matching the output impedance of the CDCVF2310 to that of the characteristic impedance of the transmission line. 12 Submit Documentation Feedback Copyright © 2001–2015, Texas Instruments Incorporated Product Folder Links: CDCVF2310 CDCVF2310 www.ti.com SCAS666D – JUNE 2001 – REVISED OCTOBER 2015 Typical Application (continued) 9.2.3 Application Curves Figure 8.

The low-noise, 125-MHz input source drives the CDCVF2310, resulting in 45-fs RMS additive jitter when integrated from 12 kHz to 20 MHz for this configuration. The low-noise 30.72-MHz input source drives the CDCVF2310, resulting in 52-fs RMS additive jitter when integrated from 12 kHz to 5 MHz for this configuration. CLK GN YN Figure 10.

Thus, it is essential to reduce noise from the system power supply, especially when jitter or phase noise is critical to applications. Filter capacitors are used to eliminate the low-frequency noise from the power supply, where the bypass capacitors provide the very low impedance path for high-frequency noise and guards the power supply system against induced fluctuations. These bypass capacitors also provide instantaneous current surges as required by the device and should have low equivalent series resistance (ESR). To properly use the bypass capacitors, they must be placed very close to the power-supply terminals and laid out with short loops to minimize inductance. TI recommends adding as many high-frequency (for example, 0.1 µF) bypass capacitors, as there are supply terminals in the package. TI recommends, but does not require, inserting a ferrite bead between the board power supply and the chip power supply that isolates the high-frequency switching noises generated by the clock buffer; these beads prevent the switching noise from leaking into the board supply. It is imperative to choose an appropriate ferrite bead with very low DC resistance to provide adequate isolation between the board supply and the chip supply, as well as to maintain a voltage at the supply terminals that is greater than the minimum voltage required for proper operation. Figure 12 shows this recommended power supply decoupling method. Board Supply VCC Chip Supply Ferrite Bead C 10 µF C 1 µF C 0.1 µF Figure 11.

For component side mounting, use 0402 body size capacitors to facilitate signal routing. Keep the connections between the bypass capacitors and the power supply on the device as short as possible. Ground the other side of the capacitor using a low-impedance connection to the ground plane. 11.2 Layout Example Ground bypass capacitor with low impedance connection to ground plane 0402 or smaller body size capacitors are recommended Place bypass power supply capacitors as short as possible to device pin Figure 12. PCB Conceptual Layout 11.3 Thermal Considerations CDCVF2310 supports high ambient temperature up to 105°C. The system designer needs to ensure that the maximum junction temperature is not exceeded. Following Equation 1 can be used to calculate the junction temperature based on the measured case temperature. The case temperature is defined as the hottest temperature on the top of the device. The case temperature measurement can be performed with (in order of accuracy) an IR camera, a fluor-optic probe, a thermocouple, or IR gun with a maximum field view of 4-mm diameter just to name a few techniques.
