Hi Pratik,

MUXout pin can be configured as PLL lock detect indicator or SDO read back operation. LED D1 is connected to MUXout pin for PLL lock detect indication, when MUXOUT_SEL = 1 and LD_EN = 1 configured. When LMX2592 PLL is locked, LED D1 will glow.

For more details see page 17 in LMX2592 datasheet for lock detect operation.

Thanks!
