Other Parts Discussed in Thread: SN75LVDS31
Dear Sirs, good afternoon!
Would you be so kind to specify some details:
1) What is the reason that there is crystal ADP3308 instead of ADP3309 in the body of the item ADP3309ARTZ-3.3-R7 ? They have different characteristics: ADP3309 - Ultralow dropout voltage - 120mV typical 100mA, ADP3308 - Ultralow Dropour Voltage - 80 mV Typical 50mA
2) Why is crystal SN75LVDS31 instead of SN65LVDS31 located in the body of the item SN65LVDS31PW? These crystals have different op temp. SN65LVDS31D has op temp from -40 to 85. And SN75LVDS31D has op temp from 0 to 70.
3) There is broken welding on the device LMH0387SL. What is the reason?
We are looking forward to your replies so much.
