Unknown Part in my Fluke 200 LAN Toner

[Glenn]

Hi Guys!

I've got a second one of these Toner Tools were this Part has been knocked of by the Coax Connector above when i dropped it.
I'm searching for the 3 legged Part labeled 6.00M. The Mask says U301, so it might be a VoltageDivider?

I've got no clue what to search for!

Can somebody help me?

What are the markings on the adjacent 14-pin IC? My first thought is that 6.00M is a 6MHz oscillator, but I've never seen one in a 6-pin package.

Crystal resonator.

This close to a connector ....I'd guess diode array for esd protection

my guess a 6.00Mhz clock generator.
