DS90CR213MTD - 21-Bit 66MHz Channel Link | Texas Instruments
MPN： DS90CR213MTD ✓ 啟用中DS90CR213MTD 概覽
A Channel Link interface is a high-speed serializing and deserializing interface that transfers multiple low-speed parallel data bits over a balanced differential link. The 21-bit width allows parallel data from a controller, processor, display, or communications equipment to be transferred efficiently over fewer conductors than a conventional parallel bus. The 66 MHz operating rate gives the interface a nominal 21-bit parallel-to-serial transfer capability of 1.386 Gb/s before protocol overhead.
The DS90CR213MTD is identified as a line-driver-class interface device in commercial catalogs. Key cataloged attributes include 48 gull-wing terminals, a TSSOP package, a 5.25 V maximum supply voltage, and a -10°C to +70°C operating-temperature range. Its 12.5 mm package length supports compact printed-circuit-board placement while preserving adequate lead spacing for automated assembly and inspection.
The EIA-644 and TIA-644 references place the device within standardized low-voltage differential-signaling interface practice. Differential signaling is valuable in systems where low voltage noise tolerance, reduced ground-reference sensitivity, and controlled signal polarity are important. The exact clocking, termination, connector, and system-bus requirements should be implemented according to the pin-description table and application guidance in the manufacturer datasheet.
Typical uses include point-to-point Channel Link connections between industrial controllers, test equipment, video or imaging subsystems, computer peripherals, and communications hardware. In each case, the 21-bit word width and 66 MHz signaling rate support compact high-speed transfers while limiting the number of inter-board conductors.
When laying out the circuit, preserve the differential-signal topology specified by the manufacturer datasheet, maintain the intended transmission-line impedance, and place termination and interface components close to their corresponding device pins. Confirm that the 5.25 V maximum supply rating, operating-temperature range, and logic levels match the intended system before releasing the layout.
This product page combines the exact catalog attributes of the DS90CR213MTD with interface guidance, drop-in family references, and application-oriented design considerations. Use the manufacturer pinout and interface-standard documentation to complete board-level signal-integrity and power-distribution decisions.

典型應用
DS90CR213MTD 適用於 6 應用s: Industrial Controller Backplane, Video and Imaging Data Transfer, Test and Measurement Instrumentation, Computer Peripheral Interconnect, Telecommunications Equipment, Medical and Diagnostic Data Modules.
Industrial Controller Backplane
The DS90CR213MTD fits point-to-point industrial backplane links that need to transfer wide controller data without a large parallel connector. Its 21-bit Channel Link width and 66 MHz operating rate produce a calculated payload rate of 1.386 Gb/s before protocol overhead. Install the device on a board using the exact pin assignments from the manufacturer datasheet, preserve the differential topology, and maintain controlled impedance between the transmitter and receiver. The 48-terminal TSSOP footprint provides a practical surface-mount solution for compact control boards, while the -10°C to +70°C commercial-temperature range is appropriate for controlled indoor equipment. Verify power-rail tolerance and grounding because the 5.25 V maximum supply rating alone does not establish every operating condition.
推薦
Video and Imaging Data Transfer
The DS90CR213MTD can support high-speed data transfer between imaging electronics and a processing section when the source produces 21-bit parallel words at 66 MHz. The calculated channel payload is 1.386 Gb/s before encoding and control overhead, making the interface appropriate for compact links between acquisition, buffering, and display-processing modules. Preserve the differential routing geometry specified by the Channel Link implementation and avoid introducing stubs on high-speed nets. The device's commercial-temperature range requires enclosure or thermal design that keeps board temperature within -10°C to +70°C. Review the manufacturer clocking, output-enable, and power sequencing guidance before integrating it with parallel-to-serial image pipelines.
推薦
Test and Measurement Instrumentation
The DS90CR213MTD is applicable in test and measurement instruments that move wide digital words between acquisition, control, and host-interface sections. A 21-bit path at 66 MHz provides a nominal 1.386 Gb/s payload and reduces the number of inter-board conductors compared with a wide parallel bus. For laboratory equipment, keep clock and data routing deterministic, observe the manufacturer's differential-signal topology, and provide stable decoupling close to the device. The 5.25 V maximum supply rating must be respected by the instrument's rail design. Because the stated temperature range is -10°C to +70°C, installations with variable ambient temperatures may require airflow or a wider-temperature replacement rather than operation outside the published range.
推薦
Computer Peripheral Interconnect
The DS90CR213MTD can be used in a computer peripheral or processor-adjacent subsystem requiring a compact, high-speed parallel-to-serial channel. Its 21-bit Channel Link width handles broad data words at 66 MHz, while the 48-terminal TSSOP package fits between larger components on a multilayer PCB. Route the interface as a controlled-impedance differential connection and place any termination components where the manufacturer's reference circuit indicates. The commercial-grade operating range suits office or controlled enclosure temperatures, but system airflow and board self-heating should be considered. Check signal polarity, clock phase, and power sequencing against the exact manufacturer datasheet to prevent interface interoperability problems between the peripheral and the host controller.
推薦
Telecommunications Equipment
The DS90CR213MTD supports compact module-to-module transfers in telecommunications equipment that must move a 21-bit parallel payload at 66 MHz. The nominal 1.386 Gb/s channel rate allows designers to reduce connector pin count while retaining a broad internal data word. Apply the manufacturer's recommended interface termination, keep clock and differential nets away from noisy switching paths, and use continuous reference planes under the routed links. The device's -10°C to +70°C operating range fits many indoor network appliances, although outdoor installations require a product rated for the actual temperature. Confirm supply sequencing and logic compatibility with the adjacent line-card controller, and use the exact 48-terminal TSSOP land pattern from the manufacturer package drawing.
推薦
Medical and Diagnostic Data Modules
The DS90CR213MTD can provide a compact internal link between diagnostic acquisition, control, and display modules where a 21-bit parallel data path is required. The 66 MHz Channel Link rate offers a calculated 1.386 Gb/s payload for moving synchronized digital samples without a wide board-to-board connector. Differential routing reduces sensitivity to common-mode noise when used according to the manufacturer's implementation guidance, but isolation, grounding, and leakage requirements remain system-specific. The commercial temperature range limits its use in uncontrolled environments, so confirm enclosure temperature and thermal rise. Because medical-system qualification depends on the complete design rather than one interface IC, validate the finished module against the applicable end-product safety and EMC requirements.

主要差異化特點
- Exact 21-bit, 66 MHz Channel Link configuration (對比DS90CR213MTD/NOPB)
- Commercial-temperature 48-terminal TSSOP implementation (對比DS90CR213)
- Standards-aligned differential interface positioning (對比DS90CR213A)
設計說明
Use the exact 48-terminal TSSOP land pattern and pin table from the manufacturer datasheet. Route the differential Channel Link nets as a controlled-impedance pair, keep the two conductors closely coupled, minimize stubs, and avoid sharing the pair with unrelated digital traffic. Place termination and interface components according to the manufacturer reference circuit rather than distributing them along the route. The EIA-644/TIA-644 interface designation indicates that differential routing discipline is central to reliable operation.
Design the supply network so the DS90CR213MTD never exceeds its specified 5.25 V maximum. Place the required local bypass capacitors at the device pins with short ground returns, and use a quiet return path that does not share narrow connections with high-current switching nodes. Validate the rail during startup, load changes, and fault conditions. The maximum rating is an absolute limit rather than the recommended operating point, so use the manufacturer operating-range guidance when selecting regulators.
Account for loss, skew, reflections, and connector transitions across the complete link rather than evaluating only the IC-to-IC segment. Keep the 66 MHz clock and 21-bit data paths arranged according to the reference implementation, and observe the manufacturer requirements for clocking, enable control, and output state. When changing connectors or cable length, re-evaluate the transmission line and termination rather than assuming that the TSSOP footprint alone guarantees compatibility.
Do not substitute a family member solely because its catalog description contains the same 21-bit width and 66 MHz rate. Confirm the complete ordering suffix, package drawing, temperature grade, lead configuration, pin functions, and interface timing requirements against the original manufacturer datasheet. In particular, the DS90CR213MTD and DS90CR213MTD/NOPB are distinct orderable codes. A PCB-level substitution is valid only after the schematic, bill of materials, and manufacturer documentation agree.
合規資訊
The catalog information identifies a commercial-temperature product but does not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The /NOPB ordering suffix appears in a product listing, but no compliance claim is inferred from that suffix.
