General Description
The CDCUN1208LP is a 2:8 fan-out buffer featuring a wide operating supply range, two universal
differential/ single ended inputs, and universal outputs (HCSL, LVDS, or LVCMOS) with clock edge rate
control. One of the device inputs includes a divider that provides divide values of /1, /2, /4, and /8. The
device is offered in a 32 pin QFN package. The CDCUN1208LP is flexible and easy to use. The
application configures the device by setting the state of certain pins at device power-up. Alternately, the
application can configure the device via SPI/I2C. The CDCUN1208LP delivers excellent additive jitter
performance, and low power consumption. The output section includes four dedicated output supply pins
enabling the operation of output ports from different power supply domains. This provides the ability to
clock devices switching at different LVCMOS levels without the need for external logic level translation
circuitry.
The evaluation module (EVM) demonstrates the electrical performance of the device. This fullyassembled, factory-tested evaluation board allows complete validation of all device functions. For optimum
performance, the board is equipped with 50Ω SMA connectors and well-controlled 50Ω impedance micro
strip transmission lines.
3
Signal Path and Control
The CDCUN1208LP provides two selectable inputs – IN1 and IN2. The IN1 and IN2 can accept either
differential (HCSL, LVDS) signals up to 400 MHz or single ended LVCMOS signals up to 250 MHz. The
CDCUN1208LP provides up to eight differential signals or sixteen single ended signals.
In pin mode the device option is selected by six control pins. In programming, mode options are selected
by programming the on-chip registers. The CDCUN1208LP datasheet provides the detailed information
needed to configure and use this device.
All outputs are connected to SMA with ac coupling. All outputs provide the options of 50 ohm to ground
(for HCSL outputs).
4
Software Selectable Option
The provided EVM Control Software communicates with the CDCUN1208LP through a USB interface and
the SPI port. The USB controller is normally powered over the USB cable. When the USB/SPI
programming interface is available for use, the on-board LED D26 is illuminated.
The CDCUN1208LP GUI also allows device configurations to be saved into a configuration file (.INI),
which can be loaded at a later time to restore the saved settings.
5
Installing the EVM Control Software and USB Driver
To start the installation of the EVM software, double-click on the file named
“CDCUN1208LP_Installer.exe”. This can be downloaded from www.ti.com/product/CDCUN1208LP/. If
Microsoft .NET Framework is not already installed on the computer, it will automatically download and
install on the computer. The installer will also attempt to install the EVM hardware driver.

Configuring the Board
www.ti.com
Each output buffer can be selected as LVDS, HCSL or a pair of LVCMOS outputs. One of the signal types
can be selected for each output or can be disabled by clicking on the output buffer box. If LVCMOS signal
type is selected, Enable boxes need to be checked to enable the outputs individually.

Configuring the Board
The CDCUN1208LP is a programmable clock buffer with many options. The EVM was designed with the
maximum flexibility so that the user can configure the EVM to operate in its desired mode.
Selecting the Interface Connection
The CDCUN1208LP can be configured via serial interface or through control pins. Switch SW17 should be
turned on to enable communication through USB to the SPI interface. This switch must be turned off for
Pin control mode. Switch SW18 must also be turned off.
Header JMP6 and JP_3_17 can also be used to connect external host to SPI/I2C.
Configuring the Power Supply
The device can be powered up with external power supply or on-board regulators powered by USB cable
attached. The EVM has options for 1.8V, 2.5V and 3.3V power supplies. These supply voltages can be
external or internal from the regulators. It has also five different rails – four for output power supplies and
one for VDD.
The banana jacks P9, P10 and P11 are external 3.3V, 2.5V and 1.8V respectively. The banana jacks P8
and P12 are for GND. The LDOs U14, U15 and U16 generate 3.3V, 2.5V and 1.8V respectively. The
jumper on Header JP_3_24 selects between external or internal 3.3V, the jumper on Header JP_3_25
selects between external or internal 2.5V and the Jumper on Header JP_3_26 selects between external or
internal 1.8V.
The Jumpers on the Header JMP5 selects for VDD power rail, JMP1 selects for VDDOUT1, JMP2 selects
for VDDOUT2, JMP3 selects for VDDOUT3 and JMP4 selects for VDDOUT4 from 3.3V, 2.5V and 1.8V
power supplies. Using these Headers, the power supplies can be mixed for the device operation.
The figure below is an example of the configuration of the power supplies – all supplies are chosen from
3.3V internal regulators.

Configuring the Reference Inputs
The CDCUN1208LP offers two inputs (IN1 and IN2). SMA J4 and J5 are dedicated for IN1 (IN1p and
IN1n) and SMA J7 and J8 are dedicated for IN2 (IN2p and IN2n). Both inputs in the EVM are ac-coupled
as default by using coupling capacitors (C231 and C232 for IN1 and C235 and C236 for IN2). JMP7 and
JMP8 are used to set the input biasing and termination and should be configured according to the Input
Reference section of the EVM schematic.
All inputs have options for 50 Ω to GND. This 50 Ω to GND can be required if the signal generator is used
as input clock source.
Configuring the Control Pins
The device has multiple dedicated pins to control and configure the operation. Setting of these pins is
critical to operate the device correctly.
Mode Selection Pins (MODE): This pin will select the mode of device configuration. The Jumper on the
Header MODE (JP_3_20) is required to set based on Table 1.
