DS90CR211MTDX - 21-Bit LVDS Channel Link Transmitter | TI
MPN: DS90CR211MTDX ✓ نشطDS90CR211MTDX نظرة عامة
Channel Link is a proprietary high-speed digital interface technology developed by National Semiconductor (now part of Texas Instruments) that reduces the number of parallel data lines by serializing them into LVDS pairs. This technology is widely used in flat panel displays, digital video interfaces, and other applications requiring high bandwidth over a limited number of wires. The DS90CR211MTDX is part of the Channel Link family, which includes transmitters and receivers that work together to provide a complete serialization/deserialization solution.
Key features of the DS90CR211MTDX include a 21-bit parallel input, three LVDS data outputs plus one clock output, and a maximum data rate of 840 Mbps. The device has a typical power consumption of and supports a wide operating temperature range of -40°C to +85°C. The LVDS outputs feature low voltage swing (typically 350 mV) and high noise immunity, making the device ideal for noisy industrial environments. The transmitter also includes a power-down mode to reduce power consumption when not in use.
The DS90CR211MTDX uses a phase-locked loop (PLL) to generate the high-speed serial clock from the parallel input clock. The PLL ensures low jitter and accurate data alignment, which is critical for reliable data transmission at high speeds. The device also features built-in termination resistors on the LVDS outputs, simplifying PCB layout and reducing external component count. The TSSOP package offers a compact footprint with a 0.65mm lead pitch, suitable for space-constrained designs.
Typical applications include flat panel displays, digital video interfaces, industrial cameras, medical imaging, and automotive infotainment systems. The device is particularly well-suited for applications requiring high-speed data transfer over long distances with minimal EMI, as LVDS signaling inherently provides low electromagnetic interference. The DS90CR211MTDX is also used in test and measurement equipment where high-speed data acquisition is required.
When designing with the DS90CR211MTDX, ensure that the LVDS output traces are impedance-matched (typically 100Ω differential) and kept as short as possible to minimize signal integrity issues. The power supply should be well-decoupled with 0.1µF and 10µF capacitors placed close to the VCC pins. The PLL requires a clean power supply to achieve optimal jitter performance, so avoid routing the power traces near high-speed switching signals.

ملاحظات التصميم
For optimal signal integrity, route the LVDS output pairs as 100Ω differential pairs with controlled impedance. Keep the traces as short as possible and avoid vias. Place a 100Ω termination resistor across each LVDS pair at the receiver end. The PLL power supply (PLLVCC) should be decoupled with a 0.1µF capacitor placed as close to the pin as possible.
The DS90CR211MTDX requires a clean 4.5V to 5.5V supply. Use a 10µF bulk capacitor and a 0.1µF ceramic capacitor near the VCC pins. The PLLVCC pin should have its own 0.1µF capacitor to minimize noise coupling into the PLL, which could increase jitter on the LVDS outputs.
Ensure the parallel input clock (CLKIN) is clean and has low jitter, as it directly affects the LVDS output jitter. Avoid routing CLKIN near high-speed switching signals. The power-down pin (PDWN) is active low; tie it high if not used. Do not leave unused inputs floating; tie them to GND or VCC as appropriate.
