Hello, how are you?
I´m working with LMK04832-SP and I need to connect a voltage controlled oscillator
to OSCin pins and I use a dual loop configuration.
I have a VCXO ACMOS, voltage controlled oscillator, with a single ended output. I don't have an Outout_P and an Output_N. Like the LMK development kit.
We can see the VCXO and LMK connection, in the Kit LMK04832EVM-CVAL, in the next picture. The clock signal is connected to pin N, LMK 44 pin, not to pin P, LMK 43 pin, and has an network with the components R58 C72 R59 R60 C71.
Also we can see the same network, with the components R58 C72 R59 R60 C71, in the ADC12DJ3200EVMCVAL kit.
I have some questions about that:
1_ Why is the oscillator single ended signal connected to pin N not to pin P, like we can see in Figure 2 and Figure 3?
2_ What is the function of the network between the voltage controlled oscillator output and the LMK input?
3_ Can I connect the oscillator single ended output to OSCinP without a network Like the Figure 1, as it says in the data sheet in figure 1 ?
Thanks you
