Channel Link is a proprietary interface technology developed by National Semiconductor (now part of Texas Instruments) that serializes parallel data into LVDS pairs. This device belongs to the family of LVDS interface ICs, which are used to transmit high-speed digital data with low power consumption and excellent noise immunity. The DS90CR283MTDX/NOPB is the 5V version of the popular DS90CR285, which operates at 3.3V, making it suitable for legacy 5V logic systems.
Key features include a 28:4 data compression ratio, a rising-edge data strobe, and a phase-locked loop (PLL) for clock generation. The transmitter accepts 28 single-ended CMOS/TTL inputs and outputs four LVDS data pairs plus one LVDS clock pair. The device supports a wide input clock range and includes a power-down mode to reduce quiescent current. The TSSOP-56 package offers a compact footprint for space-constrained designs.
Technically, the DS90CR283MTDX/NOPB uses a differential signaling scheme with a typical output voltage swing of 350 mV across a 100-ohm termination resistor. The LVDS outputs are current-mode drivers that provide low electromagnetic interference (EMI) and high noise immunity. The PLL ensures that the transmitted clock is aligned with the data, simplifying receiver timing. The device is specified for the commercial temperature range (0°C to 70°C) and is RoHS compliant.
Typical applications include flat panel displays, digital video interfaces, and high-speed data links in industrial and consumer electronics. The 5V supply makes it ideal for interfacing with legacy TTL logic. When designing with this device, ensure proper termination of the LVDS lines with 100-ohm resistors and maintain controlled impedance on the PCB to preserve signal integrity.

یادداشت‌های طراحی
For optimal signal integrity, route the LVDS output pairs as differential pairs with 100-ohm differential impedance. Keep the trace lengths matched within 5 mils to minimize skew. Place the 100-ohm termination resistor as close to the receiver input as possible. Use a solid ground plane beneath the LVDS traces to reduce EMI and crosstalk.
Decouple the VCC and PLLVCC pins with 0.1uF ceramic capacitors placed as close to the pins as possible. Additionally, use a 10uF bulk capacitor on the main VCC rail. The PLL is sensitive to power supply noise; a ferrite bead in series with PLLVCC can further isolate it. Ensure the supply voltage stays within 4.75V to 5.25V to maintain PLL lock.
The DS90CR283MTDX/NOPB typically dissipates less than 1W, but in high-temperature environments, ensure adequate airflow or a thermal pad on the PCB. The TSSOP-56 package has a theta_JA of approximately 40°C/W. For reliable operation, keep the junction temperature below 125°C. If the device is placed near other heat sources, consider adding vias under the package to improve heat dissipation.
