DS90CR483VJD - 48-Bit LVDS Serializer | Texas Instruments
MPN: DS90CR483VJD ✓ AktifDS90CR483VJD Genel Bakış
A Channel Link serializer is a high-speed parallel-to-serial interface IC used to move multiple bits of digital data across a balanced cable or PCB link. Its function sits within the broader LVDS interface and data-converter hierarchy: parallel CMOS data enters the serializer, is transmitted on eight differential outputs, and is reconstructed by a compatible deserializer such as the DS90CR484. Differential signaling improves noise immunity and supports reliable communication over longer cable runs than a single-ended parallel interface.
The DS90CR483VJD accepts 48 parallel data inputs and provides eight differential LVDS outputs. Its maximum clock frequency of 112 MHz supports increased bandwidth compared with earlier Channel Link generations. The manufacturer datasheet also identifies selectable pre-emphasis as an enhancement for improved cable drive. A 3 V supply and an LVDS output amplitude of approximately 0.45 V are identified in the product documentation.
Internally, the device acts as the transmit-side half of a Channel Link chipset. Parallel CMOS/TTL data is serialized onto eight LVDS channels, reducing the number of signal conductors required compared with a wide parallel bus. The architecture is intended to pair with the DS90CR484 deserializer, which reconstructs the transmitted word and recovers the parallel clock. This division of transmit and receive functions allows each endpoint to connect a parallel source or destination to a differential serial link.
Typical applications include high-speed industrial data acquisition, instrumentation backplanes, professional video and imaging equipment, communications infrastructure, test and measurement systems, and embedded control platforms that must transfer wide parallel words across a compact differential interface. The eight LVDS outputs can also support redundant or segmented communication paths when the complete system architecture permits it.
Designers should treat the serializer as a high-speed differential interface rather than a general-purpose logic device. Controlled-impedance routing, uninterrupted reference planes, compliant LVDS termination, and careful clock distribution are essential. The DS90CR483VJD is normally used as the transmitting endpoint, so the deserializer part number, cable length, connector, pre-emphasis setting, and system clocking must be selected together before PCB layout begins.
This product page consolidates the verified electrical identity, interface architecture, package information, replacement considerations, and practical design guidance for the DS90CR483VJD. It also separates the serializer from its complementary DS90CR484 deserializer so engineers can assess the complete chipset rather than treating a single half of the link in isolation.

Tipik Uygulamalar
DS90CR483VJD için uygundur 6 uygulamas: Industrial Data Acquisition Backplanes, Test and Measurement Instrumentation, Professional Video and Imaging Systems, Communications Infrastructure Equipment, High-Speed Instrumentation Interconnect, Embedded Parallel-to-Serial Data Links.
Industrial Data Acquisition Backplanes
The DS90CR483VJD fits parallel-to-LVDS conversion in industrial acquisition systems that collect wide sensor or processing data and move it across a backplane. Its 48 parallel inputs, eight differential outputs, 33 MHz to 112 MHz clock range, and 5.38 Gbps aggregate rate permit wide data transfers without routing a 48-bit bus long distances. Pair the serializer with a DS90CR484 at the receiving endpoint and preserve controlled-impedance routing, source-synchronous timing, proper LVDS termination, and a continuous reference plane to maintain signal integrity over the installed channel.
Önerilen
Test and Measurement Instrumentation
The DS90CR483VJD can transport acquisition results from parallel instrumentation logic to a remote processor or display system. Forty-eight simultaneous input bits map to eight LVDS channels, while the 112 MHz maximum clock and 5.38 Gbps aggregate data rate support high-throughput measurement sequences. The differential outputs are preferable to a long single-ended parallel bus because they reduce common-mode noise pickup. The receiving board should implement the DS90CR484 and validate cable length, connector geometry, pre-emphasis, and clock recovery over the full operating range.
Önerilen
Professional Video and Imaging Systems
The DS90CR483VJD is appropriate for parallel imaging and video-processing systems requiring a compact high-speed link between a source ASIC and a separate processing or display controller. Eight LVDS outputs carry the serialized representation of each 48-bit parallel word, and the 5.38 Gbps aggregate rate supports demanding data movement. Keep the serializer and deserializer on matched clocking and impedance-controlled interconnects, and validate lane skew, cable attenuation, and selectable pre-emphasis before production release.
Önerilen
Communications Infrastructure Equipment
The DS90CR483VJD can provide the transmit-side interface in communications equipment that must move a wide parallel data word from a baseband or packet-processing engine to a line-card or backplane receiver. The 48-bit parallel input and eight LVDS outputs reduce wiring demand relative to a wide external bus, while differential signaling improves noise tolerance. The board designer should use the complete Channel Link chipset, maintain return-path continuity, and confirm that the 112 MHz clock assumption remains valid across temperature and cable length.
Önerilen
High-Speed Instrumentation Interconnect
The DS90CR483VJD is useful when an instrument must separate a high-speed parallel acquisition section from a remote digital processing section. The serializer accepts 48 CMOS/TTL bits and transmits them as eight LVDS pairs, allowing the PCB or cable to use fewer conductors while preserving a high aggregate transfer rate of 5.38 Gbps. For dependable operation, use the manufacturer reference configuration, preserve differential-pair symmetry, provide suitable LVDS termination, and confirm that selectable pre-emphasis is configured for the actual interconnect loss.
Önerilen
Embedded Parallel-to-Serial Data Links
The DS90CR483VJD can bridge a parallel FPGA or ASIC interface to a differential data link when eight LVDS lanes are preferable to a long exposed parallel bus. Its 48-bit input word, 112 MHz maximum clock, and 5.38 Gbps aggregate rate support high-volume control, sensor, or packet data transfer between circuit cards. The design must account for source-synchronous clock alignment, input-output timing skew, continuous ground references, and the receive-side deserializer's clock recovery so that serialized data can be reconstructed without intermittent framing errors.

Tasarım Notları
Route every LVDS pair as a tightly coupled, length-matched differential route over a continuous reference plane. Avoid plane splits, test pads that remove return-path continuity, and unnecessary stubs beneath the pairs. Keep the serializer and deserializer ground and supply connections close to their pins. The eight differential outputs should remain symmetric because mismatched skew can shift the timing relationship between serialized data channels.
Select the cable length, connector, and pre-emphasis setting as one system-level decision rather than tuning the transmitter in isolation. The manufacturer datasheet identifies user-selectable pre-emphasis as a means of improving cable drive. Validate the selected setting with the intended receiver and interconnect because excessive pre-emphasis can increase edge distortion on short or low-loss channels.
Do not treat the DS90CR483 and DS90CR484 as interchangeable transmit and receive devices. The DS90CR483VJD serializes parallel input data, while the DS90CR484 reconstructs parallel data. Also verify the 112 MHz maximum clock against processor timing margin, board skew, and channel-loss budget. Using the correct chipset, terminating the LVDS network correctly, and confirming the complete pin assignment are essential before functional testing.
