16MHZ crystal

Hi,

Could someone help me with information on what the max allowed ESR value for the 16 MHz crystal for reliable operation is?

thx,
Thomas

Hi,

Hi,
I have one additional question related to the crystal. I am looking for a small form factor 16MHz crystal does anyone have any suggestions? I have looked at some in a 2.0 x 1.6 mm package have anyone found any smaller?

16 MHz crystal size

Hi Thomas,

the smallest standard size for 16 MHz crystals is the 2.0 x 1.6 mm package we think.
Custom made types could be smaller.
Please be aware that smaller sized crystals in general have higher ESR values.
Check the crystal's datasheet on ESR values.
If possible, when opting for a small sized crystal, choose one with a relatively low Cload value, e.g. 6 pF or 8pF i.s.o. 10 pF
This is beneficial for crystal startup time.

best regards, Dialog support

Hello,

Hello,
Could you please give me the references of a crystal, in a 2.0 x 1.6 mm package, that is known to work with the DA14580?
Thanks in advance,
Jeremy

16 MHz crystal

Hi Thomas,

the maximum allowed ESR for the 16 MHz crystal is 100 Ohm.
It's recommended though, to have typical values of 50 Ohm.
Too high ESR value will effect the crystalstartup time, and hence will negatively effect the energy consumption.

Best regards, Dialog support

Hi Jeremy,

Hi Jeremy,

following 2016 sized types will work:

River Eletec: ESR 80 Ohm max - Type: FCX-06 LF 16.000 MHz
http://www.river-ele.co.jp/index_en.html

EPSON: ESR 80 Ohm max - Type: FA-128 (new!).  Not sure it's released yet.

Best regards, BB_Dialog.

We are not aware of others suitable for the DA14580.
