Table 4-1 Pin Functions
PIN TYPE DESCRIPTION
No. NAME
1 VOP_LNA Output LNA non-inverting output
2 VOM_LNA Output LNA inverting output
3 EN_LNA Input LNA Enable, EN_LNA = 0 = Disable and EN_LNA = 1 = Enable
4 VIM_VGA Input VGA inverting Input
5 VIP_VGA Input VGA non-inverting input
6 VEE_VGA Power VGA negative supply
7 VCC_VGA Power VGA positive supply
8 EN_VICM Input

VGA internal common mode enable.

EN_VICM = 1; Input common mode = Mid Supply. For AC coupled inputs.

EN_VICM = 0; Input common mode = (VIP_VGA+VIM_VGA)/2. For DC inputs.
9 EN_VGA Input VGA Enable, EN_VGA = 0 = Disable and EN_VGA = 1 = Enable
10 VOCM_ADJ Input Output Common-Mode Voltage adjust pin.
11 VOP_VGA Output Non-inverting VGA output
12 VOM_VGA Output Inverting VGA output
13 VREF Input External reference voltage. Can be left floating to use internal VREF but TI recommends decouple to ground using 1nF capacitor.
14 GAIN_ADJ Input Gain Control Voltage
15 HILO Input Gain Range Select. High Gain Mode = HILO = 1. Low Gain Mode = HILO = 0
16 VIM_LNA Input LNA inverting input
17 VIP_LNA Input LNA non-inverting input
18 NC NC No Connect
19 VCC_LNA Power LNA positive supply
20 VEE_LNA Power LNA negative supply
— Thermal Pad — Thermal pad. Electrically isolated from the device. Recommended connection to a heat spreading plane, typically VEE.
