Product details
Overview
DS90C241QVS/NOPB from Texas Instruments is a 24-bit FPD-Link II serializer IC that converts parallel LVCMOS data (24-bit + clock) into a DC-balanced LVDS serial stream with embedded clock, operating from 5 MHz to 35 MHz. It features programmable output voltage (±400 mV or ±750 mV), pre-emphasis control for up to 10-meter cable drive, and individual transmitter power-down. It is used in automotive display interfaces requiring EMI-robust, skew-free high-speed data transmission.
For engineers reviewing the DS90C241QVS/NOPB datasheet, DS90C241QVS/NOPB pinout, DS90C241QVS/NOPB application, or DS90C241QVS/NOPB equivalent, key selection considerations include its AEC-Q100 qualification, 48-pin TQFP package, LVDS serializer function with embedded clock recovery compatibility, and support for AC-coupled interconnects without external encoding.
Technical Context
The DS90C241QVS/NOPB implements a parallel-to-serial conversion architecture with on-chip DC-balance encoding, PLL-based clock multiplication, and PTO (Progressive Turn-On) LVCMOS outputs to minimize SSO effects. Its transmitter accepts 24-bit parallel data synchronized to an LVCMOS clock (TCLK) and outputs a single LVDS differential pair (DOUT+/DOUT−).
It supports user-selectable clock edge sampling (via TRFB), programmable VOD level (VODSEL), and pre-emphasis tuning (PRE pin with external resistor). The device integrates separate analog/digital power domains (VDDPTx/VDDIT/VDDL/VDDT) and dedicated ground planes to maintain signal integrity across its 5–35 MHz operational range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Clock Range | 5 MHz to 35 MHz - defines minimum/maximum parallel clock frequency for valid serialization; impacts eye opening and jitter tolerance. |
| Data Width | 24-bit parallel input - maps directly to DIN[23:0] pins; enables full RGB888 video transport without multiplexing. |
| Output Interface | LVDS differential pair (DOUT+/DOUT−) - provides low-noise, low-power, noise-immune serial transmission over twisted-pair cable. |
| VOD Selection | ±400 mV (VODSEL = L) or ±750 mV (VODSEL = H) - selects driver strength for short PCB traces or long lossy cables respectively. |
| Power Supply | 3.3 V ±10% - requires stable single-supply rail; multiple internal VDD/VSS domains isolate analog PLL and digital logic sections. |
| Temperature Range | –40°C to +105°C - qualified for under-hood and instrument cluster automotive environments per AEC-Q100 Grade 2. |
| ESD Rating | ±8 kV HBM - ensures robustness during handling and system integration in production and field service. |
Pinout & Package
DS90C241QVS/NOPB is housed in a 48-pin TQFP package (7.00 mm × 7.00 mm body size) with exposed thermal pad (not electrically connected). Pin functions are fully defined in TI's SNLS209M datasheet, including dedicated power/ground separation for analog PLL (VDDPT0/VSSPT0), LVDS output (VDDDR/VSSDR), and digital logic (VDDL/VSSL) domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DIN[23:0] | Parallel data input | 24-bit LVCMOS inputs accepting RGB/video data; must be tied LOW if unused - floating inputs cause undefined behavior. |
| TCLK | Parallel clock input | LVCMOS clock driving parallel interface; edge (rising/falling) selected by TRFB pin; jitter ≤33 ps RMS required. |
| DEN | Data enable control | Active-High enables LVDS output drivers; when LOW, DOUT± enter TRI-STATE while PLL remains locked. |
| TPWDNB | Transmitter power-down | Active-High enables operation; LOW places transmitter in sleep mode, reducing supply current to 800 µA. |
| DOUT+/DOUT− | LVDS serial output | Differential pair driving 100-Ω terminated line; AC-coupled via 100-nF capacitors; supports pre-emphasis via PRE pin. |
| VODSEL | VOD level select | LVCMOS input selecting ±400 mV (LOW) or ±750 mV (HIGH) differential output swing for impedance/cable matching. |
Key Features
| Feature | Design Value |
|---|---|
| DC-balance encoding | Enables AC-coupled interconnects without external coding logic - eliminates DC bias drift and simplifies connector design. |
| Programmable pre-emphasis | Adjustable via external resistor on PRE pin - compensates high-frequency loss in long shielded twisted-pair cables up to 10 meters. |
| Individual power-down controls | Separate TPWDNB (transmitter) and RPWDNB (companion DS90C124 receiver) allow granular power management per link direction. |
| Embedded CDR compatibility | Serializer output waveform meets jitter and eye-opening specs (TxOUT_E_O ≥ 0.75 UI) required for reliable lock by DS90C124 deserializer. |
| PTO LVCMOS outputs | Progressive Turn-On reduces simultaneous switching output (SSO) noise - critical for maintaining signal integrity in dense automotive PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPD-Link II serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS90C365QVS/NOPB | 36-bit serializer with identical 5–35 MHz range, same 48-TQFP package, but adds spread-spectrum clocking and enhanced ESD (±12 kV HBM). | Targets higher-resolution displays (e.g., WQHD+); not drop-in due to different pin mapping and additional control pins. | Select DS90C365QVS/NOPB only when 36-bit data path or spread-spectrum EMI reduction is required - otherwise DS90C241QVS/NOPB offers optimal cost/performance for 24-bit use cases. |
| MAX9247GTJ+T | GMSL-compatible serializer (not FPD-Link II); operates up to 43 MHz, supports bidirectional control channel, uses different encoding and termination scheme. | Designed for GMSL ecosystem (e.g., with MAX9257 deserializer); requires redesign of layout, firmware, and cable assembly. | Choose MAX9247GTJ+T only when migrating to GMSL for longer reach (>15 m) or integrated sideband communication - not a functional substitute for DS90C241QVS/NOPB in existing FPD-Link II designs. |
Compared with DS90C365QVS/NOPB and MAX9247GTJ+T, DS90C241QVS/NOPB delivers proven 24-bit FPD-Link II interoperability with DS90C124, minimal BOM impact, and direct AEC-Q100 qualification - making it the optimal choice for cost-sensitive, volume automotive display links where 24-bit bandwidth suffices.

FAQ
What is the primary function of the DS90C241QVS/NOPB in an automotive display system?
The DS90C241QVS/NOPB serves as a 24-bit parallel-to-LVDS serializer that embeds clock information into a single differential data stream. In automotive display systems, it transports RGB888 video data from a graphics processor to a remote LCD panel while eliminating clock/data skew, reducing EMI, and enabling compact cabling - all within the –40°C to +105°C operating range required for dashboard and instrument cluster environments.
Does the DS90C241QVS/NOPB require an external reference clock for operation?
No, the DS90C241QVS/NOPB does not require an external reference clock. It uses the incoming parallel clock (TCLK) as its timing source and internally generates the high-speed LVDS bit clock via a PLL. The companion DS90C124 deserializer recovers this embedded clock using CDR - so no separate clock line or crystal oscillator is needed across the link.
How does the PRE pin on the DS90C241QVS/NOPB affect signal integrity over long cables?
The PRE pin on the DS90C241QVS/NOPB enables adjustable pre-emphasis by connecting an external resistor (≥3 kΩ) to ground. This boosts high-frequency components of the LVDS output, compensating for attenuation in lossy shielded twisted-pair cables up to 10 meters. Pre-emphasis improves eye opening at the deserializer input, directly enhancing bit-error-rate performance in long-reach automotive video links.
Can the DS90C241QVS/NOPB operate with a 2.5-V supply instead of 3.3 V?
No, the DS90C241QVS/NOPB is specified only for 3.3 V ±10% operation (3.0 V to 3.6 V). Its LVCMOS input thresholds, LVDS output voltage levels (VOD), and internal PLL performance are characterized and guaranteed exclusively within this supply range. Operating outside this window risks functional failure, timing violation, or non-compliance with AEC-Q100 stress requirements.
What is the purpose of the LOCK signal in the DS90C241QVS/NOPB system context?
The LOCK signal is generated by the companion DS90C124 deserializer - not the DS90C241QVS/NOPB itself - and indicates whether the deserializer's PLL has achieved and maintains lock to the incoming serialized data stream. System firmware monitors LOCK to validate data integrity before enabling display output; DS90C241QVS/NOPB enables seamless interoperability with this status flag through its standardized FPD-Link II protocol.
