Other Parts Discussed in Thread: LMK04821,
Hi again,
Here is the recommended programming sequence from Sec 9.5.1 of the manual:
1. Program register 0x000 with RESET = 1.
2. Program registers in numeric order from 0x000 to 0x165. Ensure the following register is programmed as
follows: 0x145 = 127 (0x7F)
3. Program register 0x171 to 0xAA and 0x172 to 0x02.
4. If using LMK04821, program register 0x174.
5. Program registers 0x17C and 0x17D as required by OPT_REG_1 and OPT_REG_2.
6. Program registers 0x166 to 0x1FFF.
Q1: My design uses VCO0 and does not use VCO1. Can I skip step 5?
Q2: Why doesn't VCO0 require the same special attention as VCO1?
Q3: I have the flexibility in the design to use either of the two VCOs for PLL2 feedback. Which would be the better choice? (for reference, feedback frequency is 2376MHz and DClkOut is 148.5MHz)
Hopeful thanks in advance --todd
