Table 13. Pin Function Descriptions Pin No. Type1 Mnemonic Description
A1, A2 I RX2A_N, RX2A_P Receive Channel 2 Differential Input A. Alternatively, each pin can be used as a single-ended input or combined to make a differential pair. Tie unused pins to ground. A3, M3 NC NC No Connect. Do not connect to these pins. A4, A6, B1, B2, I VSSA Analog Ground. Tie these pins directly to the VSSD digital ground on the printed B12, C2, C7 to circuit board (one ground plane). C12, F3, H2, H3, H6, J2, K2, L2, L3, L7 to L12, M4, M6 A5 I TX_MON2 Transmit Channel 2 Power Monitor Input. If this pin is unused, tie it to ground. A7, A8 O TX2A_N, TX2A_P Transmit Channel 2 Differential Output A. Tie unused pins to 1.3 V. A9, A10 O TX2B_N, TX2B_P Transmit Channel 2 Differential Output B. Tie unused pins to 1.3 V. A11 I VDDA1P1_TX_VCO Transmit VCO Supply Input. Connect to B11. A12 I TX_EXT_LO_IN External Transmit LO Input. If this pin is unused, tie it to ground. B3 O AUXDAC1 Auxiliary DAC 1 Output. B4 to B7 O GPO_3 to GPO_0 3.3 V Capable General-Purpose Outputs. B8 I VDD_GPO 2.5 V to 3.3 V Supply for the AUXDAC and General-Purpose Output Pins. When the VDD_GPO supply is not used, this supply must be set to 1.3 V. B9 I VDDA1P3_TX_LO Transmit LO 1.3 V Supply Input. B10 I VDDA1P3_TX_VCO_LDO Transmit VCO LDO 1.3 V Supply Input. Connect to B9. B11 O TX_VCO_LDO_OUT Transmit VCO LDO Output. Connect to A11 and a 1 µF bypass capacitor in series with a 1 Ω resistor to ground. C1, D1 I RX2C_P, RX2C_N Receive Channel 2 Differential Input C. Each pin can be used as a single-ended input or combined to make a differential pair. These inputs experience degraded performance above 3 GHz. Tie unused pins to ground. Rev.
