LMK05318B EVM
1
Overview
The LMK05318B EVM is an evaluation module for the LMK05318B Network Clock Generator and
Synchronizer. The EVM can be used for device evaluation, compliance testing, and system prototyping.
The EVM includes SMA connectors for clock inputs, oscillator inputs, and clock outputs to interface the
device with 50-
Ω
test equipment. The device can be configured through I2C or SPI using the onboard
microcontroller. The graphic interface TICS Pro can be used to program the LMK05318B registers and on-
chip EEPROM.
