I am using Virtex-7 FPGA (xc7vx415tffg1157) and i want to conenct Two x1 GTH transceiver port from FPGA to to SRIO switch. My SRIO speed should support upto 5Gbps. So, i need to connect reference clock for SRIO interface. Can you please tell me the clock input range for FPGA GTH port.

If you are using the SRIO core then reference clock of 125Mhz is needed to operate upto 5Gbps.
If using the wizard to support only the phy layer it supports various reference clocks which you can check using the
Refer PG007 clocking section if using the core.

Can you provide reference scheamatics for Virtex-7 FPGA with SRIO interface?

Kintex7 and Virtex7 boards can be used for SRIO connectivity,Where the GT's can be used to Implement the SRIO functionality.
There are no specific Schematics for SRIO,You can check VC707 and VC709 schematics for reference.
Have a look at below post where one of the possible connections is mentioned.
