MPN: DS90CR216MTDX/NOPB ✓ Hoạt độngDS90CR216MTDX/NOPB Tóm tắt
What is an LVDS receiver? LVDS (Low-Voltage Differential Signaling) is a high-speed, low-power interface standard used to transmit data over twisted-pair or PCB traces. An LVDS receiver is a specialized interface IC that converts differential LVDS signals back into single-ended CMOS/TTL logic levels. In the hierarchy of interface ICs, an LVDS receiver falls under the category of high-speed serializers/deserializers (SerDes) and is a key component in display interfaces, industrial video links, and automotive infotainment systems. The DS90CR216 is specifically a deserializer that reconstructs parallel data from a serialized LVDS stream.
Key features of the DS90CR216MTDX/NOPB include a 21-bit parallel output, rising-edge data strobe, and backward compatibility with existing 5V Channel Link transceivers (DS90CR213/DS90CR214). The device provides substantial cable reduction: a 21-bit wide data bus plus clock typically requires up to 44 conductors in a single-ended parallel interface, but with Channel Link, only 9 conductors (3 data pairs, 1 clock pair, and ground) are needed. This reduces cable size, cost, and EMI. The receiver also features a power-down mode and supports interconnects up to 5 meters depending on cable quality.
Technically, the DS90CR216 uses a differential signaling scheme with a typical differential output voltage of 0.45V, ensuring low electromagnetic interference and high noise immunity. The device is designed for point-to-point or multi-drop configurations and includes internal termination for the LVDS inputs. The rising-edge data strobe simplifies timing by aligning data capture with the clock edge, reducing setup/hold requirements. The receiver is specified for the industrial temperature range of -40°C to +85°C, making it suitable for harsh environments.
Typical applications include flat panel display interfaces, digital video transmission, industrial machine vision, and automotive camera links. The DS90CR216 is often paired with the DS90CR215 transmitter to form a complete Channel Link solution. When designing with this device, ensure proper PCB layout with controlled impedance traces for the LVDS pairs and place the receiver close to the connector to minimize skew. Also, provide adequate decoupling on the VCC pins with 0.1uF and 10uF capacitors.
In summary, the DS90CR216MTDX/NOPB is a robust, high-speed LVDS receiver that simplifies data transmission in space-constrained applications. Its low-voltage operation and reduced conductor count make it an efficient choice for modern digital interfaces.

Ghi chú thiết kế
For optimal signal integrity, route the LVDS differential pairs with controlled impedance (typically 100 ohms differential). Keep the trace lengths matched within 5 mils to minimize skew. Place the receiver close to the connector to reduce stub effects. Use ground planes beneath the LVDS traces to provide a return path and reduce EMI. Refer to TI's application note on LVDS PCB layout for detailed guidelines.
Decouple the VCC pins with a 0.1uF ceramic capacitor placed as close as possible to each VCC pin, and a 10uF bulk capacitor near the device. The DS90CR216 operates from 3.3V, and proper decoupling is essential to prevent power supply noise from affecting the LVDS receiver's performance. Ensure the power supply can handle the peak current during switching, which can be several hundred mA.
Do not leave the PWRDWN pin floating; tie it to VCC for normal operation or to GND for power-down. Ensure the LVDS inputs are properly terminated with 100 ohm resistors across each differential pair if not using internal termination. Verify that the LVDS clock and data lines are not swapped, as this will cause data corruption. Also, ensure the supply voltage does not exceed 3.6V to avoid damage.
