3.2 EVM Configuration

The LMKDB1204EVM can be configured for multiple modes using on board MCU and external power or USB supply options. The following sections describes power, logic, clock input, and output interfaces on the EVM and how to configure the EVM accordingly.

Some of the key components and the reference designator are noted in Table 4-1.

Table 3-1 Key Components Reference Designator and Descriptions
Item No. Reference Designators Description
1 U1 LMKDB1204.
2A J19 External VDD option through SMA port.
2B JP9 Jumper header to select between external or onboard 3.3V USB supply option.
3 J1, J2, J3, J4 SMA Ports for clock input (CLKIN#_P, CLKIN#_N).
4 J5 through J12 SMA Ports for clock outputs (CLK#_P, CLK#_N).
5 JP1 CLKPWRGD_PD# pin header jumper to enable or disable the LMKDB1204.
6 JP2 ZOUT_SEL pin header jumper to select 85Ω or 100Ω output impedance.
7 JP3 SMB_EN pin header jumper to enable or disable SMBus mode during power-up.
8 JP4 CLKIN_SEL_tri pin header jumper to select which CLKIN drives which outputs.
9 U7 USB power option LDO.
10 U5 MSP430F5529IPN MCU.
