Hello Rakesh,

What is the value of your load capacitors to ground from XL1 and XL2? Look at the connection at our reference design.  

I have asked our expert. According to the datasheet (https://no.mouser.com/ProductDetail/ABRACON/ABS05-32.768kHz-7-T?qs=XAiT9M5g4x%252BdZqLQfRhFYw%3D%3D)  CL = 7, so you can use 12pF as load capacitor.

Thanks.
