LatticeECP2/M Family Data Sheet

[LOC]_SQ_VCCIBm

—

Input buffer power supply, channel m (1.2V/1.5V). This pin should be left ﬂoat-

ing if the channel is unused.

[LOC]_SQ_VCCOBm

—

Output buffer power supply, channel m (1.2V/1.5V). This pin should be left

ﬂoating if the channel is unused.

[LOC]_SQ_HDOUTNm

High-speed output, negative channel m

[LOC]_SQ_HDOUTPm

High-speed output, positive channel m

[LOC]_SQ_HDINNm

High-speed input, negative channel m

[LOC]_SQ_HDINPm

High-speed input, positive channel m

[LOC]_SQ_VCCTXm

—

Transmitter power supply, channel m (1.2V). This pin must be tied to 1.2V

even if the channel is unused.

[LOC]_SQ_VCCRXm

—

Receiver power supply, channel m (1.2V). This pin must be tied to 1.2V even if

the channel is unused.

1. These signals are relevant for LatticeECP2M family.

2. m deﬁnes the associated channel in the Quad.

3. These signals are deﬁned in Quads [LOC] indicates the corner SERDES Quad is located: ULC (upper left), URC (upper right), LLC (lower

left), LRC (lower right).

4. When placing switching I/Os around these critical pins that are designed to supply the device with the proper reference or supply voltage,

care must be given. For more information, refer to technical note TN1159, LatticeECP2/M Pin Assignment Recommendations.
