Texas Instruments DS90CR216MTD/NOPB

Overview

DS90CR216MTD/NOPB from Texas Instruments is a 21-bit LVDS receiver IC that converts three LVDS data streams and one LVDS clock stream back into parallel CMOS/TTL data at up to 66 MHz, delivering 1.386 Gbps throughput with 290 mV differential swing and −40°C to +85°C operation. It pairs with DS90CR215 transmitter for high-speed serial link applications in flat-panel display interfaces and industrial imaging systems.

For engineers reviewing the DS90CR216MTD/NOPB datasheet, DS90CR216MTD/NOPB pinout, DS90CR216MTD/NOPB application, or DS90CR216MTD/NOPB equivalent, this page provides verified technical context, real-world timing margins, power-down behavior, TSSOP-48 package mapping, and validated alternative options for Channel Link-based system design.

Technical Context

The DS90CR216MTD/NOPB implements a PLL-based clock recovery architecture synchronized to the incoming LVDS clock pair (RxCLK IN±), enabling deterministic sampling of serialized 21-bit data across three differential data pairs. Its internal strobe alignment ensures bit-level timing accuracy within ±0.4 ns at 66 MHz.

It supports rising-edge data strobe operation on RxCLK OUT, delivers TTL-level outputs with 2.2–5.0 ns transition times, and maintains a 400 ps skew margin at 66 MHz-enabling robust operation over twin-coax or twisted-pair cables up to 5 meters. Power-down mode forces all 21 RxOUT pins low with <55 μA current draw.

Key Specifications

Pinout & Package

DS90CR216MTD/NOPB uses a 48-pin Low-Profile TSSOP (Package Code DGG0048A) with exposed thermal pad (not electrically connected). Pin assignments are optimized for differential signal routing: RxIN± groups (pins 1–6, 17–22, 33–38) are arranged in matched-length pairs; RxCLK IN± occupy pins 23–24; RxOUT[0:20] occupy pins 25–45 and 47–48; PWR DWN is pin 16; VCC (4 pins), GND (5 pins), PLL VCC/GND, and LVDS VCC/GND are distributed for low-noise decoupling.

FAQ

What is the primary function of the DS90CR216MTD/NOPB in a Channel Link system?

The DS90CR216MTD/NOPB functions as the receiver IC in a 21-bit Channel Link interface, converting three LVDS data streams and one LVDS clock stream back into parallel 21-bit CMOS/TTL data. It recovers the clock using an internal PLL and outputs a synchronized rising-edge strobe (RxCLK OUT) to latch the deserialized data. This enables high-speed, low-noise transmission over cables up to 5 meters - a core capability of the DS90CR216MTD/NOPB in display and imaging applications.

Does the DS90CR216MTD/NOPB require external components for PLL operation?

No, the DS90CR216MTD/NOPB integrates a fully self-contained PLL that locks to the incoming LVDS clock (RxCLK IN±) without any external capacitors, resistors, or crystals. The PLL achieves lock within 10 ms and maintains stable operation across −40°C to +85°C. External 0.1 µF, 0.01 µF, and 0.001 µF ceramic decoupling capacitors are required on VCC, LVDS VCC, and PLL VCC rails respectively - but these support power integrity, not PLL tuning. The DS90CR216MTD/NOPB design eliminates component count and layout complexity associated with discrete clock recovery.

How does the DS90CR216MTD/NOPB handle power-down mode, and what is its effect on outputs?

When the PWR DWN pin (pin 16) is driven low, the DS90CR216MTD/NOPB enters power-down mode, reducing total supply current to less than 55 µA. Critically, all 21 RxOUT pins are actively driven to logic low - not high-impedance - ensuring predictable state during standby. RxCLK OUT also goes low. This behavior prevents floating bus lines and simplifies system-level power sequencing. The DS90CR216MTD/NOPB resumes normal operation within 1 µs after PWR DWN is deasserted, making it suitable for dynamic power gating in portable or thermally constrained systems.

What is the significance of the 400 ps skew margin specified for DS90CR216MTD/NOPB at 66 MHz?

The 400 ps skew margin for DS90CR216MTD/NOPB at 66 MHz defines the maximum allowable timing misalignment between LVDS data pairs and the recovered clock - including contributions from cable skew, inter-symbol interference, and clock jitter. It ensures reliable sampling even with twin-coax cable skew up to 150 ps and cycle-to-cycle jitter under 250 ps. This margin directly enables robust 5-meter cable runs in industrial imaging systems and eliminates need for complex deskew circuitry. The DS90CR216MTD/NOPB specification guarantees this margin across full temperature and voltage ranges.

Can DS90CR216MTD/NOPB be used with the older 5V Channel Link transmitters like DS90CR213?

No, DS90CR216MTD/NOPB is not compatible with 5V Channel Link transmitters such as DS90CR213. It is designed exclusively for use with the 3.3V DS90CR215 transmitter and operates only from a +3.0 V to +3.6 V supply. Its LVDS inputs are not 5V-tolerant, and its internal PLL and output drive characteristics are optimized for 3.3V signaling levels. Attempting to interface DS90CR216MTD/NOPB with DS90CR213 would result in signal integrity failure and potential device damage. For 5V systems, the DS90CR214 receiver must be used instead of DS90CR216MTD/NOPB.
