CLKOUT_​S_​GEN5_​N0 O DMI Clock Output: Serial Reference differential output clocks to PCH DMI interfacing SOC-S. CLKOUT_​S_​GEN5_​P/N [0] is dedicated to be used as Intel® 800 Series Chipset DMI REFCLK only
CLKOUT_​S_​GEN5_​P0
GPP_​SB08/I_​SRCCLKREQ0# IOD Clock Request: Serial Reference Clock request signals for PCIe* 100 MHz differential clocks. The I_​SRCCLKREQ # signals can be configured to map to any of the IOE PCI Express* Root Ports while using any of the IOE CLKOUT differential pairs
GPP_​SB09/I_​SRCCLKREQ1#
GPP_​SD06/SRCCLKREQ2# IOD Clock Request: Serial Reference Clock request signals for PCIe* 100 MHz differential clocks. The SRCCLKREQ # signals can be configured to map to any of the SOC-S PCI Express* Root Ports while using any of the SOC-S CLKOUT differential pairs.

SRCCLKREQ2# pins (muxed on GPP_​SD06 and GPP_​SB00) and SRCCLKREQ3# pins (muxed on GPP_​SD07 and GPP_​SB01) are alternate signals; only one pin can be used at a time.
