Differential Global Buffer Input
All eight global buffer inputs support single-ended I/O standards such as LVCMOS. Global buffer GBUF7 in I/O
Bank 3 also provides an optional direct SubLVDS, LVDS, or LVPECL differential clock input, as shown in
The GBIN7 and its associated differential I/O pad accept a differential clock signal. A 100 Ω termination resistor is
required across the two pads. Optionally, swap the outputs from the LVDS or LVPECL clock driver to invert the
clock as it enters the iCE65 device.
Table 15
differential input is the only one that connects directly to a global buffer, other differential inputs can connect to a
global buffer using general-purpose interconnect, with slightly more signal delay.

Note the clock differences between the iCE65L04 and iCE65L08 in the CB196 package.
The differential global buffer input is not available for iCE65 devices in the CB132 package. This
restriction is an artifact of the pin compatibility between the CB132 and CB284 package.
Note the clock differences between the iCE65L04 and iCE65L08 in the CB196 package.
