  • 75 Ω N-type RF male connectors

Подробнее о продукте

The ADCA5190-EVALZ evaluation board consists of a 2-layer printed circuit board (PCB) fabricated from a 62 mil laminate mounted to an aluminum heat sink. The heat sink assists in providing thermal relief to the device as well as mechanical support to the PCB. Mounting holes on the heat sink allow attachment to larger heat sinks for improved thermal management.

The ADCA5190-EVALZ is populated with components to interface the IC to a typical cable TV (CATV) application. J1 (RF_IN) and J2 (RF_OUT) are 75 Ω, N-type, male coaxial connectors. The respective RF traces of the ports have a 75 Ω characteristic impedance. The ADCA5190-EVALZ is populated with components suitable for use over the −40°C to +100°C operating temperature range of the ADCA5190.

Access to the supply voltage (VDD) and GND is through a 3-pin header (P1) on the ADCA5190-EVALZ.

RF traces are 75 Ω microstrip at the input and output RF connectors. The package ground leads and the exposed paddle connect directly to the ground plane. Multiple vias connect the lead frame chip scale package (LFCSP) ground paddle to the bottom ground plane to provide adequate electrical conduction and thermal conduction to the heat sink. The transfer of heat from the ADCA5190-EVALZ ground to the heat sink is further facilitated by the insertion of a piece of indium approximately the footprint of the LFCSP between the ADCA5190-EVALZ bottom and the heat sink. There are no components on the bottom side of the PCB.

Consult the ADCA5190 data sheet in conjunction with the user guide when using the ADCA5190-EVALZ evaluation board.
