SCAS666D – JUNE 2001 – REVISED OCTOBER 2015
CDCVF2310 2.5-V to 3.3-V High-Performance Clock Buffer
1 Features
3 Description
•
•
•
•
•
•
The CDCVF2310 device is a high-performance, lowskew clock buffer that operates up to 200 MHz. 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.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input and output negative voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
This value is limited to 4.6 V maximum.

8 Detailed Description
8.1 Overview
The CDCVF2310 is a high-performance, low-skew clock buffer that operates up to 200 MHz. 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 2.5V and 3.3-V environment. The built-in output enable glitch suppression ensures a synchronized output enable
sequence to distribute full period clock signals.

8.3 Feature Description
8.3.1 Output Enable Glitch Suppression Circuit
The purpose of the glitch suppression circuitry is to ensure the output enable sequence is synchronized with the
clock input such that the output buffer is enabled or disabled on the next full period of the input clock (negative
edge triggered by the input clock) (see Figure 6).
The G input must fulfill the timing requirements (tsu, th) according to the Switching Characteristics table for
predictable operation.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. 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.

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.

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.

10 Power Supply Recommendations
High-performance clock buffers are sensitive to noise on the power supply, which can dramatically increase the
additive jitter of the buffer. 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.

11 Layout
11.1 Layout Guidelines
Figure 12 shows a conceptual layout detailing recommended placement of power supply bypass capacitors. 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

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. Further information can be found at SPRA953 and SLUA566
