3.2 EVM Configuration

The LMKDB1108EVM can be configured for multiple modes using on board MCU, and can be powered via USB or an external power supply. 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 3-1.

Table 3-1 Key Components Reference Designator and Descriptions
Item No. Reference Designators Description
1 U9 LMKDB1108.
2A J8 External VDD option through SMA port.
2B JP12 Jumper header to select between external or on-board 3.3V USB supply option.
3 J10, J11 SMA ports for clock input (CLKIN_P, CLKIN_N).
4 J13 through J28 SMA Ports for Clock Outputs (CLKXX_P, CLKXX_N).
5 JP3, JP4 SADR0_tri and SADR1_tri jumper header option to select different address as defined in Table 3-7.
6 JP5 SBEN pin header jumper to enable or disable SBI interface during power-up.
7 JP1 TCA_RESET pin header jumper for Input/Output (IO) Expander needs to be pulled-up for proper operation. Default configuration is set to pull-up (header connected to 1-2).
8 JP2 CLKPWRGD_PD# pin header jumper to enable or disable the LMKDB1108.
9 JP6 SLEWRATE_SEL pin header jumper to select fast or slow slew rate option.
10A J1 SBI Connector header jumper for daisy chain option.
10B J2 SBI_PRIMARY header jumper option to disable the U3A, U3B, U3C, U3D buffer part of the EVM.
11 U4 USB power option LDO.
12 U1A, U1B, U1C, U1D Hi-Z buffer part used on SBI lines for daisy chain configuration.
13 U3 MUX part to choose between MCU and IO expander option on OE#0, OE#1, and OE#4 pins.
14 U2 IO Expander used for all OE# pin controls.
15 U8 MSP430F5529IPN MCU.
