BGA23 Signal Descriptions
3.4.1
Signal Name Conventions
Signal names may contain either a port designation or a serial designation, or a combination of the
two designations. Signal naming conventions are as follows:
Port Number Only.
Individual signals that apply to a particular port are designated by the
Signal Mnemonic, immediately followed by the Port Designation. For example, Transmit
Enable signals would be identified as TxEN0, TxEN1, and TxEN2.
Serial Number Only.
A set of signals which are not tied to any specific port are designated by
the Signal Mnemonic, followed by an underscore and a serial designation. For example, a set
of three Global Configuration signals would be identified as CFG_1, CFG_2, and CFG_3.
Port and Serial Number.
In cases where each port is assigned a set of multiple signals, each
signal is designated in the following order: Signal Mnemonic, Port Designation, an
underscore, and the serial designation. For example, a set of three Port Configuration signals
would be identified as RxData0_0 and RxData0_1, RxData1_0 and RxData1_1, and
RxData2_0 and RxData2_1.

Reference Clock.
50 MHz RMII reference clock is always required. RMII
inputs are sampled on the rising edge of REFCLK,
RMII outputs are sourced on the falling edge.

Transmit Data - Port 2.
Inputs containing 2-bit parallel di-bits to be transmitted
from port 2 are clocked in synchronously to REFCLK.
1. Type Column Coding: I = Input, O = Output, OD = Open Drain output, ST = Schmitt Triggered input, TS =
Three-State-able output, SL = Slew-rate Limited output, IP = weak Internal Pull-up, ID = weak Internal pull-
Down.
2. The IP/ID resistors are disabled during H/W Power-Down mode. If a Pin is an output or an I/O, the IP/ID
resistors are also disabled when the output is enabled.
3. RxData[0:7]_0, RxData[0:7]_1, CRS_DV[0:7] and RxER[0:7] outputs are three-stated in Isolation and H/W
Power-Down modes and during H/W reset.
