NB3L208KMNGEVB NB3L208K Evaluation Board User s Manual www.onsemi.com Introduction The NB3L208K is a differential 1:8 Clock fanout buffer EVAL BOARD USERS MANUAL with High-speed Current Steering Logic (HCSL) outputs. Inputs can directly accept differential LVPECL, LVDS and HCSL signals. Single-ended LVPECL, HCSL, LVCMOS, or LVTTL levels are accepted with a proper external V TH This evaluation board manual contains: reference supply. These signals will be translated to HCSL Information on the NB3L208K Evaluation Board and eight identical copies of Clock will be distributed, Block Diagram and Board Schematic operating up to 350 MHz. Assembly Instructions This manual should be used in conjunction with the device Test and Measurement Setup Procedures datasheet, which contains full technical details on the device Bill of Materials specifications and operation.

Figure 2. Time and Frequency Domain Block Diagram Power Supplies HCSL Outputs Each VDD, VDD 0 (VX on board), GND 0 (DUTGND HCSL outputs are typically loaded and terminated with on board) and SMAGND power supply has a separate a series resistor (R ) = 33- and 50- to ground. This SERIES side-launch banana jack located on bottom side of the test can be easily accomplished by connecting the HCSL outputs board (as shown in Figure 1). to the 50- internal impedance in the oscilloscope. There are on-board R = 33- termination resistors installed SERIES for each HCSL output. 50 to Ground via SMA Connector to Oscilloscope R = 33 SERIES Figure 3. Set-Up for HCSL Output www.onsemi.com 2
