1. Type Column Coding: I = Input, O = Output, OD = Open Drain
2. The LXT97x1 supports the 802.3 MDIO register set. Specific bits in the registers are referenced using an “X.Y” notation,
3. Ports 6 and 7 are available only on the LXT9781. These pins are not bonded out on the LXT9761.
9761 Pin#
where X is the register number (0-32) and Y is the bit number (0-15).

Receive Data - Port 2. Receive data signals (2-bit parallel di-
bits) are driven synchronously to REFCLK.
Receive Data - Port 3. Receive data signals (2-bit parallel di-
bits) are driven synchronously to REFCLK.
Receive Data - Port 4. Receive data signals (2-bit parallel di-
bits) are driven synchronously to REFCLK.
Receive Data - Port 5. Receive data signals (2-bit parallel
di-bits) are driven synchronously to REFCLK.
Receive Data - Port 6. Receive data signals (2-bit parallel di-
bits) are driven synchronously to REFCLK.
Receive Data - Port 7. Receive data signals (2-bit parallel
di-bits) are driven synchronously to REFCLK.
Carrier Sense/Receive Data Valid - Ports 0 - 7. On
detection of valid carrier, these signals are asserted
asynchronously with respect to REFCLK. CRS_DVn is
deasserted on loss of carrier, synchronous to REFCLK.
Receive Error - Ports 0 - 7. These signals are synchronous
to the respective REFCLK. Active High indicates that
received code group is invalid, or that PLL is not locked.
