23 / 113 page ![]() Document Feedback CSG14K_CSG8K Functional Description Datasheet • PUBLIC DS000571 • v1-00 • 2020-Dec-15 112 │ 22 Internally, the supply regulators are not connected to the actual image sensor. Connections have to be made on PCB level (from a Vxx_H/L_OUT pin to a Vxx_H/L_IN pin). In addition, each supply regulator requires to be decoupled by a 10 µF and 100 nF capacitor. ams recommends to use at least X7R- rated ceramic capacitors. To obtain an accurate bias reference in the sensor, an external bias resistor of 15.2 k Ω must be placed between BIAS_IDAC_RES and ground. It is advised to use a low tolerance (± 1%) and low temperature coefficient (50 ppm/°C or better). Next figure shows the positive and negative voltage regulator as well as the bias connections. Figure 14: On-Chip Regulators Connection Diagram After power-up of the sensor, the recommended register settings will set the correct supply levels for these regulators. Figure 14 gives an overview of the available supply regulators, the connection to the bias pin and the required voltage on that pin. |
