www.ti.com Circuit Description 2. One can use two TI THS9001 IF amplifiers to drive the ADC by applying an input to J10. Reconfigure JP3 and JP4, such that both have pins 1 and 2 shorted. To provide power to the amplifiers, connect 5 Vdc to J18 and connect the ground return to J19. -
Page 10: Test Points
www.ti.com Circuit Description 2.2.4 Digital Outputs The LVDS digital outputs can be accessed through the J5 output connector. A parallel 100-Ω termination resistor must be placed at the receiver to properly terminate each LVDS data pair. The supplied logic analyzer breakout board includes the 100-Ω terminations at the logic analyzer probe point. If using the logic analyzer breakout board, Table 3 use for configuration details. -
