vOE0#/NC | NC | J2 | I | Completing a drop-in replacement does not require any changes on these pins. These pins are NC for both the 9QXL2001B and the LMKDB1120 and can be left floating. LMKDB1120 offers an additional active low OE function for CLK0, CLK1, CLK2, CLK3, and CLK4. These LMKDB1120 pins have internal pulldown resistors that enable the outputs by default and can be left floating. | N/A. |

VDDA | VDDR3.3 | H2 | P | Completing a drop-in replacement does not require any changes on this pin. The input receiver power supply pin name is different between the 9QXL2001B and the LMKDB1120. TI decided to follow DB2000QL’s definition for naming the input receiver power supply pin as VDDA. | No changes are required. Keep the same power filtering used for the 9QXL2001B. |

VDD | VDDA3.3 | B6 | P | Completing a drop-in replacement does not require any changes on this pin. This pin name is different between the 9QXL2001B and the LMKDB1120. TI decided to follow DB2000QL’s definition which states that the input receiver power supply pin name is VDDA. Pin B6 is not an input receiver power supply pin on the LMKDB1120 and was not labeled as such. | |

LMKDB1120 offers an additional LOS# function. This pin is open drain and can be left floating. Open drain outputs require an external pullup resistor to close the current path and generate a signal. | |
