Notes:
1_{Guaranteed by design and characterization, not 100% tested in production.}
2 _{All Long Term Accuracy specifications are guaranteed with the assumption that the input clock complies with CK420BQ/CK410B+}
accuracy requirements (+/-100ppm). The device itself does not contribute to ppm error.
3 _{Driven by SRC output of main clock, 100 MHz PLL Mode or Bypass mode}
4 _{Driven by CPU output of main clock, 133 MHz PLL Mode or Bypass mode}
