Dallas crystal clock generator with selectable frequency factor and the jitter amplitude

In Electronic Infomation Category: R | on December   1, 2010

Dallas Semiconductor recently introduced a crystal clock generator DS1080L. DS1080L internal integrated PLL (PLL), used to generate clock outputs, and OPA547T datasheet and also has three pin-selectable frequency jitter rate and OPA547T price and the three, can reduce EMI; the period jitter as low as 75ps. Provide spread-spectrum mode and OPA547T suppliers and disable DS1080L shutdown mode to save power.

DS1080L with 1,2 and 4, three kinds of pin-selectable integer frequency factor, when combined with a low-cost 16MHz to 34.4MHz crystal when used in combination, can generate 16MHz to 134MHz output frequency. The center spread pin-selectable option for the 0% jitter (disabled), ± 0.5%, ± 1.0% and ± 1.5%. In order to keep the audio range jitter rate, the spread-spectrum jitter rate is fixed at fIN/1024. Uses spread-spectrum DS1080L as the system clock can simplify or even eliminate shielding and filtering measures, which can reduce costs and maximize design time. 3.0V to 3.6V
DS1080L supply by working at -40 ℃ to +125 ℃ automotive temperature range. Device is a tiny, 8-pin μSOP package, starting at $ 0.87 (10,000-up, FOB USA).
