1. Functional Description
The evaluation kit can be used to evaluate the 8V19N850, a fully integrated radio synchronizer and JESD204B/C
clock jitter attenuator. The kit can be used toevaluate major parameters including phase noise, spurious
attenuation, clockfrequency,output skew, phase alignment,device timing,and the signal waveform. The device
on the board accepts any input frequency from 1Hz to 1GHz. Locked to a selected input, the device PLLs
generate clock and SYSREF signals for converter reference frequency and data frame synchronization.
The 8V19N850 supports two independent frequency domains:one generates transport network clocks,such as
Ethernet frequencies at four outputs and the other one generates radio base station clocks at 12 outputs
(ADC/DAC reference clocks and SYSREF signals). Each frequency domain usesa DPLL forfrequency
translation, clock filtering,and jitter attenuation. The DPLLs provide a programmable bandwidth and a DCO
function for real-time frequency/phase adjustment.
1.1 Operational Characteristics
The board is equipped with on-board LDOs that require a 4V supply. The input power voltage should not exceed
5V. The board is designed to operate over the industrial temperature range from -40 to 85°C, ambient
temperature.
It is recommended that the person operating the board use proper grounding to avoid ESD damage to the EVB.

Connect the board as shown in Figure 2. See more details below:
■Power connection:
●Set the power supply voltage to 4V and the current limitto 2.5A
●+4V (J50) = +4V
●GND (J51) = GND
■Expected currentdraw
●Rakon TCXO not populated: ~ 1.5A
●Rakon TCXO populated. Initial current draw will be ~2A and then it will drop down to ~1.7A (Rakon TCXO
draws about 250mA after it stabilizes.)
●After programming the device, depending on the configuration, ~1.1A to 1.7A during normal operation.
■USB/I2C Connection
●Connect the USB port (J55) to PC through USB Cable
■For proper functionality out of the box, the jumpers on board should be placed to allow the correct voltages at
each LDO and domain. The jumpers should be arranged as seen in Table 1.

1.3 GUI Setup and Configuration
1.3.1. Prepare the Software
1. Prior to execution of the GUI, the Timing Commander software must be downloaded and installed.
If Timing Commander is already installedon the computer, skipthis step.
2. Download the 8V19N850D_vx.tcp file from the 8V19N850 webpage.
3. Download and unzip the 8V19N850D_Example_Configuration_files.zip found on the 8V19N850 webpage.
These configurations match the four default configuration settings from the internal read-only storage spaces
that is specified by the GPIO pins 0, 1.
4. If Timing Commander is not yet installed,please download and install the software from the Timing
Commander webpage.
Figure 2. TimingCommander Download
5. Double click on the TimingCommanderSetup.exe file.
6. Follow the on-screen instructions.
1.3.2. Bring Up the GUI
1. After successfully installing the Timing Commander software, activate the software from the Windows
<start> menu at the bottomleft-corner of the screen.
2. Start > IDT> Timing Commander.

1.4 Hardware Modification Options
There are three options forproviding an input signal to the device XO_DPLL (crystal oscillator input for System
Digital PLL) pin:
■An external signal (J7/J9 SMA connectors) typically from a signal generator; see Section 1.4.1).This option is
configured by default.
■An on-board OCXO (U3: OCXO, mounted on the board); see Section 1.4.2
■An on-board TCXO (U4: TG7050, footprint for TCXO), see Section 1.4.3.
The following sections describe how to configure the board foreach option.
1.4.1. Overdrive the OCXO (TCXO) with an External Signal Source
1. Power off the on-board TCXO by removing the JP2 jumper.
2. Apply a single-ended signal to J7 or a differential signal to J7/J9 from an external signal source (e.g., Lab
Low noise Signal Generator, RS SMA100A). See an example cable connection in the following image. The
signal must meetthese requirements:
■~1.6Vpp to ~3Vpp for single-ended input
■~800mVpp to ~1.5Vpp for differential
■Option 1 circuit (default Assembly)
