TUSB7340: CRYSTAL OSC GND CONNECTION

Tool/software:

Hi there,

I am following the TUSB7340 evaluation schematic and I have a question about the crystal oscillator ground connection.
The crystal used in the design is ABM3B-48.000MHZ-B2-T from Abracon and on its datasheet there are two ground connections as shown below:

In the TI schematic, the ground pins 2 & 4 are not shown (see below).

Are pins 2 & 4 connected to ground?

Sincerely,
Girish
