MEMS resonator, 40.608 MHz CMOS output
Supply range and stability across temperature
Rated supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails with margin. Frequency stability is ±10 ppm over the -20°C to 70°C operating range — tight enough for 100BASE-T Ethernet clocking or a UART baud-rate reference where cumulative ppm error must stay below 1%. The 6-SMD, No Lead Exposed Pad package measures 7.00 mm x 5.00 mm with a seated height of 0.90 mm, a standard footprint that routes to inner layers without via-in-pad.
