Dual 124.2 MHz LVDS clock from a MEMS resonator
Supply range, stability, and temperature grade
Frequency stability is ±25 ppm over -20°C to 70°C, which keeps the clock edge jitter within budget for most 124.2 MHz SERDES interfaces without needing a TCXO.
The 14-VFQFN exposed-pad package measures 3.20 mm x 2.50 mm with a 0.90 mm seated height — the thermal pad under the package must be soldered to a PCB ground plane for heat sinking and mechanical stability.
This part is safe to design into new production runs today.
