Help needed Identifying a crystal osc.

Can anyone please help ID this part? Even finding the manufacturer would be
a massive help.
I'm told it came from a Sony PS3 remote controller if that narrows the
search.
Many thanks.

If you don't know whence it came, you're probably not looking
to replace a dead part.
I'd guess it is some form of oscillator.
They're usually the same power pinout as a 7400 gate.
Power and ground in opposite corners. Third corner is output.
Fourth corner is sometimes an inhibit/enable pin.
I'd start at 3.3V and measure the frequency. If it ain't runnin'
try 5V.
Stability specs are something else again. If it came from a PS3
remote controller, stability doesn't have to be very good.

It's possible that it's just a crystal or other resonator If you have
continuity
between any two adjacent pins, it's more likely a resonator.
But the reverse is not necessarily true.

Could be "Canadian Marconi". Not sure whether they are still in the
crystal oscillator business but you could ask:

One of my engineers asked me if could ID the part. He buys/repairs/rebuilds
various electronic gadgets.


I think that's exactly what he wants to do.


I'll pass on your advice. Many thanks.

It's Murata, and a crystal alone, but IDing it in a shrinking product
line will be a chore.

You should be able to figure out what is needed by circuit function.
