Texas Instruments DS99R124QSQE/NOPB

Overview

DS99R124QSQE/NOPB from Texas Instruments is an automotive-grade FPD-Link II to FPD-Link deserializer IC that converts a single-pair AC-coupled serial stream (5–43 MHz, 140 Mbps–1.2 Gbps) into 3 LVDS data channels + 1 LVDS clock channel, plus 3 low-speed LVCMOS outputs and real-time LOCK status reporting. It supports RGB666 + HS/VS/DE video timing and operates across −40°C to +105°C.

For engineers reviewing the DS99R124QSQE/NOPB datasheet, DS99R124QSQE/NOPB pinout, DS99R124QSQE/NOPB application, or DS99R124QSQE/NOPB equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive AEC-Q100 Grade 2 compliance, exact LVDS output voltage control (±250 mV / ±400 mV), and real-world BIST mode behavior - all critical for display interface design in navigation and infotainment systems.

Technical Context

The DS99R124QSQE/NOPB implements a fully autonomous CDR PLL with no reference clock required, achieving FAST random-data lock in ≤6 ms at 5 MHz (SSCG off) and ≤8 ms at 43 MHz (SSCG on). Its DC-balanced decoding enables reliable AC-coupled STP interconnect up to 10 meters without training sequences or SYNC patterns.

It integrates adjustable input equalization (EQ gain: ~1.625 dB or ~13 dB), spread-spectrum clock generation (±0.5% to ±2% deviation, 8–100 kHz modulation), and dual-voltage LVCMOS I/O support (1.8 V or 3.3 V) for flexible host processor interfacing. The device also provides optional I²C-compatible serial control and hardware strap configuration for SSC, VODSEL, OSS_SEL, and LFMODE.

FAQ

What is the primary function of the DS99R124QSQE/NOPB in an automotive display system?

The DS99R124QSQE/NOPB serves as an FPD-Link II to FPD-Link deserializer, converting a high-speed, single-pair serial video stream (5–43 MHz) into parallel LVDS data and clock signals for driving TFT-LCD panels. It recovers embedded clock and data without external reference, supports RGB666 + HS/VS/DE timing, and delivers real-time LOCK status - making it essential for navigation and infotainment displays in vehicles.

Does the DS99R124QSQE/NOPB require an external reference clock to achieve lock?

No, the DS99R124QSQE/NOPB does not require an external reference clock. Its integrated CDR PLL achieves FAST random-data lock directly from the embedded clock within the FPD-Link II serial stream - eliminating the need for training sequences, SYNC patterns, or separate clock traces. Lock time is ≤6 ms at 5 MHz (SSCG off) and ≤8 ms at 43 MHz (SSCG on), as confirmed in the SNLS318D datasheet.

How does the VODSEL pin affect the DS99R124QSQE/NOPB's LVDS output performance?

The VODSEL pin on the DS99R124QSQE/NOPB selects between two differential output voltage levels: ±250 mV (VODSEL = 0) for standard EMI-limited applications, or ±400 mV (VODSEL = 1) for longer cable runs or de-emphasis-heavy channels. This selection directly impacts signal integrity margin and noise immunity - with higher VOD improving eye opening at the receiver but increasing radiated emissions.

Can the DS99R124QSQE/NOPB be used with both 1.8 V and 3.3 V host interfaces?

Yes, the DS99R124QSQE/NOPB supports dual-voltage LVCMOS I/O via its VDDIO supply rail, which accepts either 1.8 V ±5% or 3.3 V ±10%. All control pins (PDB, OEN, VODSEL, SSC[2:0], etc.) and LVCMOS outputs (LOCK, OS[2:0], PASS) operate correctly across both voltage domains - enabling seamless integration with 1.8 V microcontrollers or 3.3 V display timing controllers without level-shifting.

What is the role of the CMF pin on the DS99R124QSQE/NOPB, and how should it be configured?

The CMF (Common-Mode Filter) pin on the DS99R124QSQE/NOPB provides access to the virtual ground center-tap of the internal LVDS input termination. To improve common-mode noise rejection - especially in high-EMI automotive environments - a ≥4.7 µF capacitor should be connected from CMF to system ground. This configuration enhances immunity to coupled noise without affecting differential signal integrity or requiring external components on the RIN+/RIN− path.
