Loop-within-a-loop oscillator design ensures reliable starting without use of critical components Frequency depends on crystal, which can be anywhere in range from 1 to 20 MHz IC can be 54L00 for 1-2 MHz、standard 54H00 for 2-6 MHz, and 54H00 or 54S00 for 6-20 MHz. Temperature stability is adequate for crystal clocks and other digital-system applications.-J. E. Buchanan, Crystal-Oscillator Design Eliminates Start-Up Problems, EDN Magazine, Feb. 20, 1978, p 110.
