What are the key features of DS90CR484AVJD?
- 48-bit parallel-to-serial LVDS Channel Link transmitter reducing 48 LVTTL lines to 7 LVDS pairs, cutting cable connector pin count by 85%
- EIA-644/TIA-644 compliant differential outputs with 0.25 V minimum output swing for robust noise immunity over long PCB traces or cables
- 100-pin PQFP package integrating full 48-channel serialization in a single IC, eliminating multi-chip discrete LVDS buffer arrays
- Matched pair with DS90CR483A receiver for a complete point-to-point Channel Link solution in flat-panel display and machine-vision backplane designs
What is DS90CR484AVJD used for?
The DS90CR484AVJD is designed for flat-panel display interface applications where 48-bit pixel data buses must be transmitted with low EMI over board-to-board or cable-to-display links. It is also widely used in industrial machine-vision cameras, medical imaging panels, and rugged military avionics displays where LVDS differential signaling provides noise immunity over the required link distances. The device pairs with the DS90CR483A deserializer to form a complete high-density serializer/deserializer channel for any 48-bit parallel bus.

Frequently Asked Questions
How many LVDS output pairs does the DS90CR484AVJD use to serialize its 48-bit input bus, and at what clock rate?
The DS90CR484AVJD serializes 48 parallel LVTTL inputs into 7 LVDS differential output pairs plus a forwarded clock pair. At a 40 MHz pixel clock, each LVDS pair transmits data at 280 Mbps, allowing the full 48-bit bus to cross a single ribbon cable or PCB connector with far fewer wires than a parallel interface.
What differential signaling standard does the DS90CR484AVJD comply with, and what is the minimum output swing?
The device complies with EIA-644 and TIA-644 LVDS standards, guaranteeing a minimum differential output swing of 0.25 V into a 100-ohm termination resistor. This low-swing differential signaling suppresses common-mode noise and reduces power consumption compared to LVTTL or PECL single-ended alternatives on the same signal path.
Which receiver IC is pin-compatible with the DS90CR484AVJD for a complete point-to-point link?
Texas Instruments' DS90CR483A is the matching 48-bit LVDS Channel Link deserializer that pairs with the DS90CR484AVJD transmitter. Together they form a complete serializer/deserializer link, converting 48 parallel LVTTL inputs to 7 LVDS pairs and back to 48 LVTTL outputs with maximum cable lengths exceeding 10 meters at standard data rates.
What package does the DS90CR484AVJD use, and how does it help with PCB routing in display designs?
The DS90CR484AVJD is housed in a 100-pin PQFP (S-PQFP-G100) with a 0.65 mm pitch. This quad flat pack provides perimeter pin access that simplifies routing the 48 input data lines on a display backplane, and the single-chip integration of all 48 serializer channels removes the need for multiple smaller LVDS buffer ICs and their associated passive termination networks.
When should a designer choose the DS90CR484AVJD over a simple flat-cable LVTTL interface for connecting a display panel?
A designer should choose the DS90CR484AVJD when the display link exceeds 30 cm, when EMI regulations prohibit high-frequency parallel LVTTL switching across an unshielded cable, or when connector size is constrained. Serializing 48 bits to 7 LVDS pairs reduces the connector from 48+ pins to 8 pairs (16 pins), shrinks cable width, and keeps differential switching noise below radiated emission limits at 280 Mbps per lane.
