Texas Instruments DS90CR216AMTDX/NOPB

Overview

DS90CR216AMTDX/NOPB from Texas Instruments is a 21-bit LVDS-to-LVCMOS deserializer IC used as a receiver in high-speed video interface systems. It converts three LVDS data streams and one LVDS clock (20–66 MHz) into 21-bit parallel 3.3-V LVCMOS outputs (18-bit RGB + HSYNC/VSYNC/DE), with PLL-based clock recovery, <270 mW typical power at 66 MHz, and −40°C to +85°C operation - deployed in automotive infotainment displays and industrial imaging subsystems.

For engineers reviewing the DS90CR216AMTDX/NOPB datasheet, DS90CR216AMTDX/NOPB pinout, DS90CR216AMTDX/NOPB application, or DS90CR216AMTDX/NOPB equivalent, this page delivers verified electrical specs, TSSOP-48 package mapping, real-world timing margins (RSKM = 400 ps @ 66 MHz), power-down behavior, and direct alternatives for display link redesigns.

Technical Context

The DS90CR216AMTDX/NOPB implements a dedicated Channel Link I receiver architecture with an internal PLL that locks to incoming LVDS clock (20–66 MHz) and generates a clean RxCLKOUT strobe edge for sampling 21-bit LVCMOS outputs. Its deserialization logic reconstructs 7 bits per LVDS lane per clock cycle across three data lanes, yielding 21 total bits.

It requires external 100-Ω differential termination on each of its five LVDS inputs (RxIN0±, RxIN1±, RxIN2±, RxCLKIN±), supports 3.3-V LVCMOS output drive, and features a dedicated PWR DWN pin enabling <55 μA power-down current while holding outputs low - critical for EMI-sensitive display interconnects over cables or PCB traces.

Key Specifications

FAQ

What is the maximum data rate supported by DS90CR216AMTDX/NOPB?

The DS90CR216AMTDX/NOPB supports an LVDS clock input range of 20–66 MHz. At 66 MHz, each of the three LVDS data lanes operates at 462 Mbps, delivering a total throughput of 1.386 Gbps. This enables 18-bit RGB video at resolutions up to 1280×800 @ 60 Hz with 6-bit color depth. The device does not support higher clock rates or wider data paths beyond its 21-bit specification.

Does DS90CR216AMTDX/NOPB require external components for PLL operation?

No, DS90CR216AMTDX/NOPB integrates a fully functional PLL with no external components required. The PLL locks to the incoming LVDS clock (20–66 MHz) and generates the RxCLKOUT strobe used to sample the 21-bit LVCMOS outputs. External bypass capacitors (e.g., 0.1 µF ceramic) are required on all VCC pins per TI layout guidelines, but no resistors, capacitors, or crystals are needed for PLL functionality.

How is the DS90CR216AMTDX/NOPB powered, and what are the supply domain requirements?

DS90CR216AMTDX/NOPB uses three independent supply domains: VCC (3.0–3.6 V) powers LVCMOS outputs and logic; PLL VCC powers the phase-locked loop; and LVDS VCC powers LVDS input receivers. Each domain requires local 0.1-µF ceramic decoupling to GND. Separating these supplies minimizes noise coupling between analog (LVDS/PLL) and digital (LVCMOS) sections, preserving jitter performance and signal integrity.

What is the function of the PWR DWN pin on DS90CR216AMTDX/NOPB?

The PWR DWN pin on DS90CR216AMTDX/NOPB is an active-low LVCMOS input that places the device into ultra-low-power shutdown mode when asserted. In this state, all RxOUT[20:0] outputs are driven low, RxCLKOUT stops toggling, and supply current drops to ≤55 μA. This feature enables dynamic power gating in portable or thermally constrained display systems without requiring full power rail cycling.

Can DS90CR216AMTDX/NOPB be used with non-TI Channel Link transmitters?

Yes, DS90CR216AMTDX/NOPB is compatible with any TIA/EIA-644-compliant LVDS transmitter operating within 20–66 MHz clock range and delivering three data lanes plus one clock lane. It has been validated with TI's DS90CR215 and DS90CR285 transmitters, but interoperability depends on meeting setup/hold timing, skew margin (RSKM ≥ 400 ps @ 66 MHz), and proper LVDS termination - not manufacturer identity.
