Description

RESP_[ULC/URC]

Calibration resistor to be placed between this pin and either ground or

RESPN_[ULC/URC]. RESPN_[ULC/URC] is available on select pack-

ages. If available, connection of calibration resistor between

— RESP_[ULC/URC] and RESPN_[ULC/URC] takes precedence over

connection of calibration resistor between RESP_[ULC/URC] and

ground. Note: only one per side of the device. Value: 4.02K ohm

+/- 1% ohm.

RESPN_[ULC/URC]

Available on selected packages. If available, calibration resistor should

—

be placed between RESP_[ULC/URC] and RESPN_[ULC/URC]

instead of between RESP_[ULC/URC] and ground. Note: only one per

side of the device. Value: 4.02K ohm +/- 1% ohm.

[A:D]_VDDIBx_[L/R]

—

Input buffer power supply for channel x (1.2V/1.5V) on left [L] or right

[R] side of device.

[A:D]_VDDOBx_[L/R]

—

Output buffer power supply for channel x (1.2V/1.5V) on left [L] or right

[R] side of device.

[A:D]_VDDAX25_[L/R]

—

Auxiliary power for input and output termination (2.5V) on left [L] or

right [R] side of device.

1. The ispLEVER software tools may specify VDDRX, VDDTX, VDDP and VCCL pins. These pins should be considered VCC12 pins.

Note: Signals listed as Signal A / Signal B define the same physical pin that is used for different functions based on configuration

mode.
