Texas Instruments DS90CR216AMTD

Overview

DS90CR216AMTD from Texas Instruments is a 21-bit LVDS-to-LVCMOS deserializer IC used as a high-speed serial link receiver in display interface systems. It converts three LVDS data lanes plus one LVDS clock into 21 parallel 3.3-V LVCMOS outputs (18-bit RGB + HSYNC/VSYNC/DE), supports 20–66 MHz input clock rates, delivers ≤90 mA supply current at 66 MHz, and operates across −40°C to +85°C.

For engineers reviewing the DS90CR216AMTD datasheet, DS90CR216AMTD pinout, DS90CR216AMTD application, or DS90CR216AMTD equivalent, this page provides verified technical context, real-world timing margins, package-specific layout guidance, and validated alternative parts for display interface design, automotive infotainment, and industrial imaging systems.

Technical Context

The DS90CR216AMTD implements a fully integrated PLL that locks to incoming LVDS clock signals (20–66 MHz) without external components, enabling precise sampling of serialized 3× LVDS data streams. Its internal deserialization logic reconstructs 21-bit parallel LVCMOS output data with rising-edge strobing on RxCLKOUT, achieving 1.386 Gbps aggregate throughput at 66 MHz.

It features dedicated LVDS input termination support (100-Ω differential), separate power domains for LVDS inputs (LVDS VCC/GND), PLL (PLL VCC/GND), and LVCMOS outputs (VCC/GND), and a dedicated PWR DWN pin enabling <55 μA power-down mode. Receiver skew margin (RSKM) is specified at 400 ps (66 MHz) and 490 ps (40 MHz), directly supporting robust timing in cable or PCB trace interconnects.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LVDS deserializer applications.

Compared with DS90CR286AMTD, DS90CR216AMTD offers lower pin count, reduced routing complexity, and optimized power for 18-bit RGB systems; SN65LVDS32 lacks PLL, deserialization, and multi-bit output - making it unsuitable as a functional alternative for display link applications.

FAQ

What is the maximum supported pixel clock frequency for DS90CR216AMTD?

The DS90CR216AMTD supports LVDS input clock frequencies from 20 MHz to 66 MHz. At 66 MHz, it achieves 1.386 Gbps aggregate throughput, enabling resolutions such as 1280×800@60Hz with 18-bit RGB. The device's RSKM of 400 ps at 66 MHz ensures timing margin for real-world interconnects. DS90CR216AMTD does not support clocks beyond 66 MHz per its datasheet specifications.

Does DS90CR216AMTD require external components for PLL operation?

No, DS90CR216AMTD integrates a fully self-contained PLL that locks to the incoming LVDS clock without any external crystals, capacitors, or resistors. This simplifies design, reduces bill-of-materials cost, and improves layout reliability. The PLL operates across the full 20–66 MHz input range and delivers low-jitter RxCLKOUT with <250 ps cycle-to-cycle jitter when paired with compliant transmitters like DS90CF5624.

How many LVDS differential pairs does DS90CR216AMTD accept?

DS90CR216AMTD accepts exactly four LVDS differential pairs: three for serialized data (RxIN0±, RxIN1±, RxIN2±) and one for the clock (RxCLKIN±). Each pair requires a 100-Ω termination resistor placed as close as possible to the IC pins. This 3-data + 1-clock configuration is fixed and matches the DS90C124 or DS90CF5624 transmitter family.

What is the function of the PWR DWN pin on DS90CR216AMTD?

The PWR DWN pin on DS90CR216AMTD is an active-low LVCMOS input that places the device into ultra-low-power mode when asserted. In this state, all RxOUT outputs drive low and supply current drops to <55 μA maximum. The pin requires no external pull-up; it may be tied directly to GND for permanent enable or controlled by a processor GPIO. Recovery time from power-down is 1 μs.

Is DS90CR216AMTD compatible with standard LVDS signaling?

Yes, DS90CR216AMTD is fully compliant with the TIA/EIA-644 LVDS standard. It accepts standard LVDS differential input voltages (±100 mV threshold, 350 mV min swing), supports 100-Ω termination, and interoperates with industry-standard LVDS transmitters including TI's DS90C124, DS90CF5624, and compatible third-party sources. Its LVDS receiver inputs meet ESD ratings of ±7 kV HBM.
