SNLS272Q – APRIL 2007 – REVISED APRIL 2013

There are three supply connections (see bypass discussion in POWER SUPPLIES and also PIN

DESCRIPTIONS for recommendations). The two main supplies are the 3.3V rail and the 2.5V rail. There is also

a 3.3V connection for the PLL circuitry.

There are multiple Ground connections for the device. The main ground connection for the SER is through the

large center DAP pad. This must be connected to ground for proper device operation. In addition, multiple other

inputs are required to be connected to ground as show in Figure 17 and listed in PIN DESCRIPTIONS.
