Product details
Overview
DS99R124QSQX/NOPB from Texas Instruments is an automotive-grade FPD-Link II to FPD-Link deserializer IC that converts a single-pair 5–43 MHz serialized interface (140 Mbps–1.2 Gbps) into three LVDS data streams and one LVDS clock output, supporting 18-bit RGB666 + HS/VS/DE video timing for automotive navigation and entertainment displays.
For engineers reviewing the DS99R124QSQX/NOPB datasheet, DS99R124QSQX/NOPB pinout, DS99R124QSQX/NOPB application, or DS99R124QSQX/NOPB equivalent, key selection criteria include its AEC-Q100 Grade 2 qualification, integrated input equalization for 10-meter STP cables, lock-detection reporting via LOCK pin, and dual-voltage (1.8 V / 3.3 V) LVCMOS I/O compatibility.
Technical Context
The DS99R124QSQX/NOPB implements a clock-data recovery (CDR) PLL with fast random-data lock capability-no reference clock, training sequence, or SYNC pattern required-and supports DC-balanced decoding for AC-coupled interconnects up to 10 meters. Its embedded FPD-Link II protocol handling includes automatic scrambling, randomization, and overhead bit management (24 payload + 4 overhead bits per cycle).
It features configurable spread-spectrum clock generation (SSCG) with ±0.5% to ±2% deviation and 8–100 kHz modulation frequency, adjustable LVDS output voltage (±250 mV or ±400 mV), and optional I²C-compatible serial control bus for register-level configuration alongside strap-pin setup.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Low-Speed Outputs | 3× over-sampled LVCMOS outputs (OS[2:0]) - limited to ≤TxCLK/5, mapped to DIN21–DIN23 on companion serializers |
| Lock Detection | Real-time LOCK pin - active-high indicates stable CDR lock; used for system readiness signaling and BIST coordination |
| Power Supply | VDDIO supports 1.8 V ±5% or 3.3 V ±10% - enables direct interfacing with 1.8 V display logic or 3.3 V host systems |

Pinout & Package
DS99R124QSQX/NOPB uses a 48-pin WQFN package (RHS0048A), 7 mm × 7 mm, 0.5 mm pitch, thermally enhanced DAP grounded to PCB ground plane via ≥9 vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RIN+, RIN− | FPD-Link II differential input | AC-coupled LVDS receiver pair with internal 80 Ω termination; accepts embedded-clock serial stream |

| LOCK | Real-time link status indicator | Open-drain LVCMOS output; HIGH = CDR locked and outputs valid; used for system synchronization |
| PDB | Power-down mode control | LVCMOS input with internal pull-down; LOW forces power-down state, reducing IDD to ≤0.4 mA |
| VODSEL | LVDS output voltage select | Selects ±250 mV (short cable) or ±400 mV (long cable/de-emphasis); sets drive strength for signal integrity |
| OEN | FPD-Link output enable | Tri-states all LVDS outputs when LOW; allows dynamic power gating without affecting internal CDR operation |
| CMF | Common-mode filter tap | Access to internal termination center-tap; 4.7 μF capacitor to GND improves noise immunity in high-EMI environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar FPD-Link II deserializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS99R125QSQX/NOPB | Pin-compatible upgrade with extended 5–65 MHz range and improved jitter tolerance (≤75 ps at 65 MHz) | Supports higher-resolution displays (e.g., 1280×720) and faster pixel clocks beyond DS99R124QSQX/NOPB's 43 MHz limit | Choose DS99R125QSQX/NOPB for new designs requiring >43 MHz operation or tighter jitter budgets. |
| DS90UR241QSQX/NOPB | Integrated serializer-deserializer pair; requires companion DS90UR241Q on source side, not standalone deserializer | Used in full bidirectional FPD-Link II link implementations-not drop-in replacement for DS99R124QSQX/NOPB-only deserialization | Choose DS90UR241QSQX/NOPB only when designing complete serializer+deserializer systems with matched timing. |
Compared with DS99R124QSQX/NOPB, DS99R125QSQX/NOPB extends bandwidth and jitter performance for next-gen displays, while DS90UR241QSQX/NOPB serves as a co-located transceiver rather than a functional alternative-making DS99R124QSQX/NOPB optimal for cost-sensitive, single-ended deserialization in Grade 2 automotive displays.

FAQ
What is the maximum cable length supported by DS99R124QSQX/NOPB?
DS99R124QSQX/NOPB supports AC-coupled shielded twisted-pair (STP) interconnects up to 10 meters in length. This is achieved through adjustable input equalization (EQ gain up to 13 dB) and robust jitter tolerance (>0.45 UI at 43 MHz), enabling reliable operation with long cable runs typical in automotive cabin layouts.
Does DS99R124QSQX/NOPB require an external reference clock?
No, DS99R124QSQX/NOPB does not require an external reference clock. Its integrated CDR PLL achieves fast random-data lock directly from the embedded clock in the FPD-Link II serial stream-eliminating need for training sequences, SYNC patterns, or separate clock sources, simplifying system design and reducing BOM cost.
How is the LOCK pin used in DS99R124QSQX/NOPB system integration?
The LOCK pin on DS99R124QSQX/NOPB provides real-time status of CDR lock: HIGH indicates stable clock/data recovery and valid FPD-Link outputs, while LOW signals loss of lock. It is commonly used to gate display enable signals, trigger firmware initialization, or coordinate BIST mode activation in automotive display subsystems.
Can DS99R124QSQX/NOPB operate with both 1.8 V and 3.3 V I/O levels?
Yes, DS99R124QSQX/NOPB supports dual-voltage LVCMOS I/O via VDDIO pin: it operates with either 1.8 V ±5% or 3.3 V ±10%, allowing seamless interface with 1.8 V display timing controllers or 3.3 V host processors without level-shifting circuitry.
What is the purpose of the CMF pin on DS99R124QSQX/NOPB?
The CMF (Common-Mode Filter) pin on DS99R124QSQX/NOPB provides access to the center-tap of the internal LVDS input termination. Connecting a 4.7 μF capacitor from CMF to ground enhances common-mode noise rejection-critical in high-EMI automotive environments where RIN+/RIN− signals traverse noisy harnesses.
