Crystal Y1 may be either SMT or leaded. It is the
reference clock for all the device internal circuits.
Crystal characteristics of 10pF load capacitance,
30ppm, ESR < 50Ω, -40ºC to +85ºC temperature
range are desired. Table 5 shows the crystal
frequencies for WB or NB and one of Micrel’s
approved crystal manufacturers (www.hib.com.br).
