TMP92CZ26A

92CZ26A-23

TMP92CZ26A has two PLL circuits: one is for CPU (PLL0) and the other for USB (PLL1).
Each PLL can be con trolled independently. Frequency of external oscillator is 6 to 10MHz.
Don’t conn ec t oscill at or m ore than 10 MH z. When clo ck is in put by usin g ext ernal osci llato r,
range of input frequency is 6 to10MHz. Don’t input the clock over 10MHz.
