ZHCSE36D August 2015 – April 2018 LMK03328
PRODUCTION DATA.
Figure 84 shows the power up sequence of the LMK03328 in both the hard pin mode and soft pin mode. In the event of device power up from ROM or EEPROM, TI recommends locking one of the PLLs before the other (for cases where both PLLs are used to generate the required output frequencies) to avoid any injection locking issues in case both VCOs operate in close vicinity.
