Product details
Overview
DS90CR215MTDX/NOPB from Texas Instruments is a 21-bit LVDS transmitter IC that converts parallel CMOS/TTL data into three differential LVDS data streams plus one LVDS clock stream, operating at up to 66 MHz with 1.386 Gbps aggregate throughput and 290 mV differential output swing. It implements rising-edge data strobe timing, supports +3.3V single-supply operation, and targets high-speed video/data interconnect in flat-panel display interfaces.
For engineers reviewing the DS90CR215MTDX/NOPB datasheet, DS90CR215MTDX/NOPB pinout, DS90CR215MTDX/NOPB application, or DS90CR215MTDX/NOPB equivalent, this page delivers verified technical context, exact pin functions, real-world bandwidth and skew margins, power-down behavior, and validated alternative options for Channel Link system design.
Technical Context
The DS90CR215MTDX/NOPB integrates a PLL-based clock multiplier and serializer to convert 21 parallel TTL inputs into four LVDS differential pairs (three data, one clock), with all outputs synchronized to the rising edge of TxCLK IN. Its internal phase-locked loop requires no external components and locks within 10 ms.
It supports full 21-bit parallel input mapping per clock cycle, delivers channel-to-channel skew ≤250 ps, and maintains receiver input skew margin ≥400 ps at 66 MHz - enabling robust operation over twin-coax or twisted-pair cables up to 5 meters. Power-down mode reduces total current to <55 μA while tri-stating LVDS outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - Enables direct integration into +3.3V logic domains without level-shifting. |
| Data Throughput | 1.386 Gbps - Achieved at 66 MHz clock with 21 bits/cycle across 3 LVDS lanes, supporting VGA+ video rates. |
| Differential Output Swing | 250–450 mV - Compliant with TIA/EIA-644 LVDS standard; ensures low EMI and noise immunity. |
| Common Mode Range | +1.125 V to +1.375 V - Centered at +1.2 V, allowing ±1.0 V ground offset tolerance between boards. |
| Operating Temperature | −40°C to +85°C - Qualified for industrial and automotive display subsystems requiring extended thermal range. |
| Power Consumption | Typ. 42 mA @ 66 MHz - Total chipset (Tx+Rx) <250 mW, enabling thermally constrained embedded designs. |
| ESD Rating | >7 kV HBM - Protects against handling damage during assembly and field service. |
Pinout & Package
DS90CR215MTDX/NOPB uses a 48-lead TSSOP package (Package Code DGG0048A), with dedicated power/ground domains for TTL logic, LVDS drivers, and PLL circuitry to minimize noise coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TxIN[0:20] | CMOS/TTL Data Input | 21-bit parallel input bus sampled on rising edge of TxCLK IN; unused pins must be tied to GND. |
| TxCLK IN | TTL Clock Input | Rising-edge data strobe; accepts 3.3V logic levels only (not 5V tolerant). |
| TxOUT+[0:2], TxOUT−[0:2] | LVDS Data Output | Three differential pairs carrying serialized 21-bit payload; require 100Ω termination at receiver. |
| TxCLK OUT+, TxCLK OUT− | LVDS Clock Output | Differential clock pair transmitted alongside data; enables synchronous recovery at receiver. |
| PWR DWN | Active-Low Control | Asserting low places all LVDS outputs in high-impedance state and reduces supply current to <55 μA. |
| VCC, LVDS VCC, PLL VCC | Power Supply Inputs | Separate 3.3V rails for logic, LVDS drivers, and PLL-decoupling required per domain to suppress jitter. |
| GND, LVDS GND, PLL GND | Ground Terminals | Isolated ground returns prevent noise injection between signal domains; mandatory for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Single +3.3V supply operation | Eliminates need for dual-rail power design and simplifies PCB layout for display interface modules. |
| Rising-edge data strobe architecture | Synchronizes all 21-bit sampling to one clean clock edge, reducing setup/hold timing constraints. |
| Integrated PLL with no external components | Reduces BOM count and board area; eliminates tuning variability in high-volume display manufacturing. |
| Narrow interconnect (9 conductors max) | Replaces 44-wire parallel bus with 4 LVDS pairs + 1 ground, cutting cable cost, size, and shielding needs by ~80%. |
| 290 mV LVDS swing and +1V common-mode range | Ensures compatibility with standard LVDS receivers and tolerance to ground potential differences across connectors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LVDS serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum clock frequency supported by DS90CR215MTDX/NOPB?
The DS90CR215MTDX/NOPB supports a maximum transmit clock frequency of 66 MHz, delivering 1.386 Gbps aggregate data throughput across its three LVDS data lanes and one clock lane. At this rate, each 21-bit parallel word is serialized into seven 3-bit symbols per clock cycle, with measured channel-to-channel skew ≤250 ps ensuring reliable sampling at the receiver.
Does DS90CR215MTDX/NOPB support 5V logic inputs?
No, DS90CR215MTDX/NOPB does not support 5V logic inputs. Its TxIN and TxCLK IN pins accept only 3.3V TTL/CMOS levels (VIH = 2.0 V min, VIL = 0.8 V max) and are not 5V tolerant. Connecting 5V signals may damage the device. Level translation is required when interfacing with legacy 5V systems.
How does the power-down mode function on DS90CR215MTDX/NOPB?
When the PWR DWN pin is driven low, DS90CR215MTDX/NOPB places all LVDS outputs (TxOUT± and TxCLK OUT±) into high-impedance TRI-STATE and reduces total supply current to <55 μA. The PLL remains active but outputs are disabled, allowing fast wake-up (<100 ns delay) without re-locking. This mode is essential for dynamic power management in portable and automotive displays.
What termination is required for DS90CR215MTDX/NOPB LVDS outputs?
DS90CR215MTDX/NOPB LVDS outputs require 100Ω differential termination at the receiver end - one resistor across each LVDS pair (TxOUT+/−, TxCLK OUT+/−). The resistor value should match the cable's differential characteristic impedance (typically 90–120Ω). Surface-mount resistors placed adjacent to receiver pins minimize stub effects and preserve signal integrity.
Is DS90CR215MTDX/NOPB pin-compatible with DS90CR213?
No, DS90CR215MTDX/NOPB is not pin-compatible with DS90CR213. While functionally backward-compatible in system-level operation (same 21-bit Channel Link protocol), DS90CR215MTDX/NOPB uses a 48-pin TSSOP package with separate power/ground domains (VCC, LVDS VCC, PLL VCC), whereas DS90CR213 uses a 44-pin PLCC package with shared supplies. PCB redesign is required for migration.
