Other Parts Discussed in Thread: MSP430F2132
Dear all,
our customer would like to use MSP430 on their Project ("Gateways to gassensor").
For this they would need to have a very stabile Baud rate over the entire temperature range.
This is why they consider using a 16MHz-crystall with a max ESR of 80Ohm
According to the data sheet (msp430g2744.pdf), crystals up to 16MHz can be used if XTS = 1 and LFXT1Sx = 2.
In chapter 5.23 "Typical Characteristics - LFXT1 Oscillator in HF Mode (XTS = 1)", Figure 5-16 shows the max. ESR for the respective frequency. With "LFXT1Sx = 2" only values up to 8 MHz are available.
They compared this figure with that of the MSP430F2132 and saw that the characteristics are almost identical, but the names are different.
"LFXT1Sx = 3" is specified, although it is an external signal source and not a crystal.
So I wanted to ask how high the max ESR of the crystal can be? or whether they can use this or not.
Thanks in advance.
Regards,
Brian
