LTC6990 or LTC6900 appears to have higher error (1.5% vs 0.65% according to datasheet). If power consumption is not a concern for me, are there other parts that offer better frequency accuracy and stability while being resistor programmable? Or LTC6906…

The best way to power down the LTC1799 or the LTC6900 is to use the applications circuit "Shutting Down the LTC1799" shown on page 14 of the LTC1799 data sheet. Since these parts do not draw much current, you can easily power thrm through any one on many…

Hi rahmaevao,

The EVAL-ADM3053EBZ evaluation board demonstrates the pcb layout techniques and external components used to meet EN55022 Class B emissions. The LTC6900 low power oscillator is used to provide stimulus to the ADM3053 isolated CAN transciever…

My apologies for the delayed reply. Our web system did not forward this to me as it should. The LTC6900 has a standard CMOS output much like any typical 74HC00 logic type. It is definitely not intended to drive a 50 ohm load or anything like that. The…

There can be several possible things at work here. For now, let's assume that all of the digital communication is correct.

One possibility is capacitive loading on the output. The output driver is reasonably strong, but if the output is driving some…

Wassim,

I intend to use external oscillator LTC6900 which starts very fast (tens of microseconds) so it probably can be turning on by EXT_WAKE.

Though, the BF’s internal crystal-based oscillator (CLKIN-XTAL) could be better case, but I don’t know, how…
