However, I'm not sure if I can solder that package by hand. It seems to be similar to this:
**broken link removed**
Which I could solder by hand (I think) because the pads are on the side, in addition to below. It'd be like soldering an 0805 resistor/cap/etc.
Also, according to the datasheet, Vdd is 3.3V. Does this mean I need a seperate 3.3V regulator for the oscillator? Can I connect the oscillator's output to chip that has a 5V supply?
Hi Matt,
Dont worry!
Both oscillators has the same/similar side-wall contacting, up to ca 1mm is a gold "pin" on the sides to find -and solderable too, but you need a very fine solder tip!
Good luck!
@Wp100,
XTALs can you become nowaday in same packaging/with same soldering problematics...

Hi Keith,
You are fully correct!
I makes i.e. my footprints over long time so, that the pads are pro side minimum a half mm overhangig, longer_I have had never problems by (hand)soldering.
In all cases so small SMD will be soldered with modern and feinst soldering tips.
But we know it.
Best greetings!

I have done this already, but I have a problem with the oscillator starting. It's a 4-layer board in a low noise environment. I've tried several oscillators, and they just don't start! I don't know what to do!
However, if I give a 50% duty cycle PWM signal to the XIN pin, the chip works fine...
Hi,
You can find from RCA/Motorola & Phipse very good (but old ..) ApplNotes over XTAL Oscis with CMOS gates... Search for that pls.
Some time is a parallel resitor between in/out pins needed (normally its onchip), than others has a solution with a paar KOhm (<=10KOhm) between XTAL and oscPin2,
assumed of course, that your capacitancese are matched to your Quartz! Do varying that at 20+/- 5pF i.e.
Good luck!
