SERDES0 Signal Descriptions SIGNAL NAME [1] PIN TYPE [2] DESCRIPTION [3] ALY PIN [4] AND PIN [4] SERDES0_REFCLK_N IO Serdes Reference Clock Input/Output (negative) AU9 AK15 SERDES0_REFCLK_P IO Serdes Reference Clock Input/Output (positive) AU8 AK14 SERDES0_REXT (1) I External Calibration Resistor AN11 AG7 (1) An external 3.01 kΩ ±1% resistor must be connected between this pin and VSS. No external voltage should be applied to this pin. Table 5-87. SERDES1 Signal Descriptions SIGNAL NAME [1] PIN TYPE [2] DESCRIPTION [3] ALY PIN [4] AND PIN [4] SERDES1_REFCLK_N IO Serdes Reference Clock Input/Output (negative) AV3 AN5 SERDES1_REFCLK_P IO Serdes Reference Clock Input/Output (positive) AV4 AN6 SERDES1_REXT (1) I External Calibration Resistor AL9 AH9 (1) An external 3.01 kΩ ±1% resistor must be connected between this pin and VSS. No external voltage should be applied to this pin. Table 5-88. SERDES2 Signal Descriptions SIGNAL NAME [1] ((2)) PIN TYPE [2] DESCRIPTION [3] ALY PIN [4] AND PIN [4] SERDES2_REFCLK_N IO Serdes Reference Clock Input/Output (negative) AV21 SERDES2_REFCLK_P IO Serdes Reference Clock Input/Output (positive) AV22 SERDES2_REXT (1) IO External Calibration Resistor AL20 (1) An external 3.01 kΩ ±1% resistor must be connected between this pin and VSS. No external voltage should be applied to this pin. (2) DDRSS2, DDRSS3, and SERDES2 are not available on the 27mm package variant of this SoC. DDRSS2/DDRSS3/SERDES2 should be avoided if software compatibility is desired with systems that use the 27mm package. www.ti.com AM69A, AM69 SPRSP92C – FEBRUARY 2023 – REVISED JUNE 2024 Copyright © 2024 Texas Instruments Incorporated Submit Document Feedback 117 Product Folder Links: AM69A AM69 |
