Texas Instruments DS99R106SQ/NOPB

Overview

DS99R106SQ/NOPB from Texas Instruments is a 24-bit LVDS deserializer IC that recovers embedded clock and parallel data from a single serial LVDS stream over shielded twisted-pair cable. It operates at 3–40 MHz input clock rates (72–960 Mbps serial throughput), features integrated 100 Ω receiver termination, 4 mA LVCMOS output drive, and supports AC-coupled interfaces via internal DC-balanced encoding/decoding. It is used in flat-panel display interconnects where skew-free, low-EMI, high-density data transfer replaces wide parallel buses.

For engineers reviewing the DS99R106SQ/NOPB datasheet, DS99R106SQ/NOPB pinout, DS99R106SQ/NOPB application, or DS99R106SQ/NOPB equivalent, this page delivers verified functional identity, validated pin roles, confirmed timing behavior across all 24 data groups, real-world jitter tolerance (±0.25 UI), and precise alternative selection guidance for display link redesigns.

Technical Context

The DS99R106SQ/NOPB implements an embedded-clock CDR architecture with no external reference required. Its PLL locks to incoming serial data using pattern-independent acquisition, achieving lock in 5–50 ms depending on frequency (3–40 MHz) and data transition density.

It decodes DC-balanced serialized data into three independent 8-bit LVCMOS output groups (ROUT[7:0], [15:8], [23:16]) with group-specific setup/hold windows referenced to RCLK, and provides LOCK status flag assertion upon stable synchronization - enabling live-pluggable system behavior per RDL (Random Data Lock) compliance.

Key Specifications

FAQ

What is the primary function of the DS99R106SQ/NOPB in a display system?

The DS99R106SQ/NOPB acts as the receiver in a 24-bit LVDS SerDes pair, converting a single serial LVDS stream with embedded clock back into a parallel 24-bit LVCMOS interface (RGB + sync signals). In display systems, it enables compact, low-skew, EMI-resistant transmission from graphics source to LCD driver - directly replacing bulky parallel ribbon cables. DS99R106SQ/NOPB performs clock recovery, data deserialization, and output latching without external reference clocks.

Does DS99R106SQ/NOPB require an external reference clock to operate?

No, DS99R106SQ/NOPB does not require an external reference clock. It uses an embedded-clock CDR (Clock and Data Recovery) architecture that extracts timing information directly from the incoming LVDS serial stream. The LOCK output pin indicates successful PLL lock to the recovered clock, and the RCLK output provides the synchronized timing reference for the parallel data outputs. DS99R106SQ/NOPB achieves full "plug-and-lock" operation independent of data pattern.

How does DS99R106SQ/NOPB handle jitter on the incoming LVDS signal?

DS99R106SQ/NOPB tolerates up to ±0.25 UI (Unit Interval) of input jitter before bit errors occur, as measured by RxIN_TOL_L and RxIN_TOL_R parameters. This jitter margin is maintained across its full 3–40 MHz operating range and enables robust operation with lossy cables or noisy environments. DS99R106SQ/NOPB's CDR dynamically adapts to varying jitter profiles without retraining - a key enabler for live-pluggable applications.

Can DS99R106SQ/NOPB be used with AC-coupled interconnects?

Yes, DS99R106SQ/NOPB supports AC-coupled interconnects via its internal DC-balanced encoding/decoding scheme. The device accepts AC-coupled LVDS inputs on RIN+/RIN− pins (using 100 nF capacitors per TI recommendation) and requires no external encoding logic. This eliminates baseline wander and enables galvanic isolation between boards - essential for medical or industrial systems with ground potential differences. DS99R106SQ/NOPB implements this transparently in hardware.

What is the significance of the LOCK output pin on DS99R106SQ/NOPB?

The LOCK output pin on DS99R106SQ/NOPB is an active-high, open-drain status flag indicating stable CDR lock to the incoming serial data stream. When LOCK is high, the deserializer has achieved phase and frequency alignment with the embedded clock and is delivering valid, synchronized parallel data on ROUT[23:0] and RCLK. If LOCK goes low, all parallel outputs enter tri-state - providing hardware-level fault signaling for system diagnostics. DS99R106SQ/NOPB asserts LOCK only after verified data integrity, not just PLL lock.
