Texas Instruments DS90CR216MTD

Overview

DS90CR216MTD from Texas Instruments is a 21-bit LVDS receiver IC for Channel Link serial interface applications, converting three LVDS data streams and one LVDS clock stream into parallel 21-bit CMOS/TTL output data with rising-edge strobing. It operates at up to 66 MHz clock frequency, delivers 1.386 Gbps aggregate throughput, supports −40°C to +85°C industrial temperature range, and uses a single +3.3V supply. It is used in high-speed digital video interconnects between FPGAs, image sensors, and display controllers.

For engineers reviewing the DS90CR216MTD datasheet, DS90CR216MTD pinout, DS90CR216MTD application, or DS90CR216MTD equivalent, this page provides verified technical context, real-world timing behavior (e.g., RSPos0 = 0.7–1.4 ns @ 66 MHz), power-down current (<55 μA), LVDS input skew margin (400 ps), and precise package mapping to 48-lead TSSOP (DGG0048A).

Technical Context

The DS90CR216MTD implements a PLL-based clock recovery architecture that locks to the incoming LVDS clock pair (RxCLK IN±) and regenerates a clean TTL clock (RxCLK OUT) synchronized to recovered data. Its internal sampling window is defined by measured strobe positions (RSPos0–RSPos6) across PVT, enabling deterministic setup/hold margins.

It accepts three differential LVDS data pairs (RxIN± ×3) and one differential LVDS clock pair, reconstructing 21-bit parallel TTL outputs with 2.2–5.0 ns CMOS/TTL transition times. Power-down mode forces all RxOUT pins low while drawing <55 μA, and it complies fully with TIA/EIA-644 LVDS electrical standards including 290 mV differential swing and +1.2 V common-mode voltage.

Key Specifications

FAQ

What is the maximum supported clock frequency for DS90CR216MTD?

The DS90CR216MTD supports a maximum transmit clock frequency of 66 MHz, enabling 1.386 Gbps aggregate data throughput. At this rate, its receiver achieves a 400 ps skew margin and maintains full specification compliance across −40°C to +85°C. Operation beyond 66 MHz is not characterized or guaranteed per TI SNLS129D Rev D.

Does DS90CR216MTD require external components for PLL operation?

No, DS90CR216MTD requires no external components for PLL operation. Its internal PLL locks to the incoming LVDS clock pair (RxCLK IN±) within 10 ms and generates a clean RxCLK OUT strobe. External bypass capacitors (0.1 µF, 0.01 µF, 0.001 µF) are required on VCC, PLL VCC, and LVDS VCC rails per TI layout guidelines-but no resistors, capacitors, or crystals are needed for PLL functionality.

How does DS90CR216MTD handle power-down mode?

When PWR DWN is asserted low, DS90CR216MTD drives all 21 RxOUT pins to logic low and reduces total supply current to less than 55 μA. Unlike legacy 5V Channel Link receivers, it does not retain previous output states-outputs are actively forced low. The RxCLK OUT stops toggling, and the PLL remains inactive until PWR DWN is deasserted.

What is the LVDS input common-mode voltage range for DS90CR216MTD?

The DS90CR216MTD LVDS receiver accepts a common-mode input voltage range of 0 V to 2.4 V, centered nominally at +1.2 V. This ±1.0 V tolerance accommodates ground potential differences between transmitter and receiver boards, making it robust in multi-board systems with separate power domains or long cables.

Can DS90CR216MTD be used with the DS90CR215 transmitter?

Yes, DS90CR216MTD is the designated receiver companion to the DS90CR215 transmitter. They form a matched Channel Link chipset operating at +3.3V, supporting 21-bit data, rising-edge strobing, and 66 MHz clock rates. TI explicitly validates interoperability in SNLS129D, including timing alignment (e.g., RSPos0 matching TPpos0), skew budget allocation, and termination guidance.
