LMX2571: PLL supporting dual output

Part Number: LMX2571
Other Parts Discussed in Thread: CDCM6208

Hi Team,

I'm looking for PLL supporting following requirement.

LMX2571 has dual output but it is selected by internal MUX so LMX2571 doesn't support simultaneous outputs.

Could you let me know if we have any recommended device supporting below requirement?

[Requirement]

Output 1: 300MHz

Output 2: 300MHz ± xkHz ~ x0kHz

Key feature: need simultaneous output 1 and 2.

Regards,

Kai

    Hi Nomiyama-san,

    LMX2571 can be configured to have both outputs enabled simultaneously. Make both OUTBUF_TX_EN_Fx and OUTBUF_RX_EN_Fx = 1.

    I think CDCM6208 can support the requirement  as it has fractional output divider.
