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.

It might help if you disclosed why you want to know.
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:

Thanks for the links, but I don't think the logo matches the CMC one.

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

If you don't know whence it came, you're probably not looking
to replace a dead part.

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.
