LMK04828: LMK04828 vs LMK04610

Hello Rohith, 
The LMX0461x were semi-digital jitter cleaners PLLs designed by a team in Germany. 
These devices were designed as a stopgap between the LMK0482x jitter cleaners and the DPLLs (network synchronizers) our product line offers. 

Unfortunately, we have very limited support due to reasons outside our control and the device has a few known bugs. SYNC/SYSREF aren't too deterministic & the skew across outputs can be around 100s of ps across PVT. 

LMK0482x family are the third generation of jitter cleaners that added JESD204B, smaller dividers, clock redundancy & hold over.  The only difference between all LMK0482x parts is just the VCO frequency range. 

LMK04832 is p2p with the LMK0482x family that has much better divide by 1 performance, simplified & improved SYSREF architecture & MUXES to route SYSREF & device clocks to any output, larger output range, high-performance divider bypass in CML mode, the odd outputs support LVCMOS, you can reset R or N dividers, various new zero-delay modes, doubled the PLL2 PFD frequency maximum for better phase noise performance & most importantly - it's available in various options such as space grade (-SP), automotive grade (-Q1) , enhanced plastic, (-EP) & space enhanced plastic (-SEP).

For new designs, please adopt LMK0428x or LMK04832.  

 Best regards,
