Product details
Overview
DS90CR215MTD/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 total throughput and 290 mV differential output swing. It implements rising-edge data strobing, supports +3.3 V single-supply operation, and integrates a PLL requiring no external components. It is used in high-speed serial link applications such as flat-panel display interfaces and industrial camera data transmission.
For engineers reviewing the DS90CR215MTD/NOPB datasheet, DS90CR215MTD/NOPB pinout, DS90CR215MTD/NOPB application, or DS90CR215MTD/NOPB equivalent, key selection considerations include its 48-pin TSSOP package, 21-bit parallel-to-serial conversion capability, LVDS compliance per TIA/EIA-644, −40°C to +85°C operating range, and power-down mode consuming <0.5 mW.
Technical Context
The DS90CR215MTD/NOPB employs a phase-locked loop (PLL) to generate and synchronize the LVDS transmit clock with input data, enabling deterministic timing alignment across all 21 bits. Its internal architecture multiplexes 21 TTL/CMOS inputs into three 7-bit LVDS data lanes plus one dedicated clock lane, achieving 7× serialization per channel.
It uses current-mode LVDS drivers with 250–450 mV differential output voltage and ±35 mV matching between complementary outputs, ensuring low EMI and robust noise immunity. The device supports precise pulse positioning (e.g., TPPos0 = −0.4 to 0.3 ns at 66 MHz) and maintains channel-to-channel skew ≤250 ps, critical for maintaining receiver sampling margin.
Key Specifications

| Data Throughput | 1.386 Gbps - Achieved at 66 MHz clock rate, supporting real-time video and high-bandwidth sensor data transport. |
| Differential Output Swing | 250–450 mV - Ensures reliable LVDS signaling with low EMI and >200 mV noise margin against differential interference. |
| Operating Temperature | −40°C to +85°C - Qualified for industrial and embedded environments including automotive infotainment displays. |
| Power Consumption | 42–55 mA typical at 66 MHz - Delivers <250 mW chipset power with power-down mode reducing total draw to <0.5 mW. |

| Channel Skew | ≤250 ps - Guarantees tight timing alignment across all LVDS data lanes for accurate multi-bit recovery at receiver. |
Pinout & Package
DS90CR215MTD/NOPB is housed in a low-profile 48-lead TSSOP package (Package Code DGG0048A), with exposed thermal pad not electrically connected. Pin assignments are validated per TI SNLS129D datasheet Figure 3 and Pin Descriptions table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TxIN[0:20] | Parallel CMOS/TTL data input | 21-bit wide synchronous bus accepting rising-edge-strobed TTL/CMOS signals; unused pins must be tied to GND. |
| TxCLK IN | Input clock reference | Rising edge serves as data strobe; accepts 3.3 V TTL levels; requires <5 ns transition time for stable PLL lock. |
| TxOUT+[0:2], TxOUT−[0:2] | LVDS differential data outputs | Three 7-bit LVDS data lanes (21 bits total); each pair requires 100 Ω termination at receiver side. |
| TxCLK OUT+, TxCLK OUT− | LVDS differential clock output | Transmits synchronized clock alongside data; enables receiver clock recovery without separate reference. |
| PWR DWN | Active-low power-down control | Drives all LVDS outputs into high-impedance state; reduces supply current to <55 μA when asserted. |
| VCC, LVDS VCC, PLL VCC | Separate power domains | Independent 3.3 V supplies for logic, LVDS drivers, and PLL reduce noise coupling and improve jitter performance. |
| GND, LVDS GND, PLL GND | Isolated ground returns | Dedicated ground paths prevent switching noise from corrupting PLL or LVDS signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| 21-bit parallel-to-serial conversion | Reduces 21-signal parallel bus to only four LVDS differential pairs (3 data + 1 clock), cutting cable count by ~80%. |
| Rising-edge data strobe | Synchronizes all 21 input bits on TxCLK IN rising edge, eliminating setup/hold timing constraints on source logic. |
| Integrated PLL with no external components | Eliminates need for external crystal or loop filter, simplifying BOM and board layout while maintaining <250 ps jitter. |
| LVDS compliance per TIA/EIA-644 | Ensures interoperability with industry-standard LVDS receivers and guarantees common-mode range of +1.0 V around +1.2 V. |
| Power-down mode with <0.5 mW consumption | Enables dynamic power gating in battery-sensitive or thermally constrained systems without disrupting system-level reset sequencing. |

FAQ
What is the maximum data rate supported by the DS90CR215MTD/NOPB?
The DS90CR215MTD/NOPB supports a maximum data throughput of 1.386 Gbps at a 66 MHz transmit clock frequency. This is achieved by serializing 21 bits per clock cycle across three LVDS data lanes (7 bits per lane) plus one LVDS clock lane. The device is characterized for stable operation up to this rate across the full −40°C to +85°C temperature range, with verified pulse positioning and skew margins per TI SNLS129D.
Does the DS90CR215MTD/NOPB require external components for PLL operation?
No, the DS90CR215MTD/NOPB integrates a fully self-contained PLL that requires no external crystals, capacitors, or resistors. As confirmed in the TI SNLS129D datasheet, the PLL locks to the incoming TxCLK IN signal and generates the necessary internal timing for serialization without any external components-reducing BOM cost and board area while improving reliability.
What is the recommended termination for DS90CR215MTD/NOPB LVDS outputs?
The DS90CR215MTD/NOPB LVDS outputs require a 100 Ω differential termination resistor placed as close as possible to the receiver inputs (e.g., DS90CR216). This value matches the nominal differential impedance of standard LVDS cabling and ensures proper signal integrity. TI explicitly states no pull-up or pull-down resistors are needed, and surface-mount resistors are preferred to minimize parasitic inductance.
Can the DS90CR215MTD/NOPB operate with a 5 V input interface?
No, the DS90CR215MTD/NOPB accepts only 3.3 V CMOS/TTL input levels and is not 5 V tolerant. Its VIH minimum is 2.0 V and VIL maximum is 0.8 V under 3.3 V supply, and applying 5 V signals risks permanent damage. For legacy 5 V systems, TI recommends upgrading to the 3.3 V supply domain and using level translators if interfacing with older controllers.
How does the power-down mode affect DS90CR215MTD/NOPB outputs and supply current?
When PWR DWN is asserted low, the DS90CR215MTD/NOPB places all LVDS outputs (TxOUT± and TxCLK OUT±) into high-impedance TRI-STATE and reduces total supply current to <55 μA (typical). This mode preserves signal integrity on shared buses and cuts static power to near-zero, making it ideal for dynamic power management in portable or thermally sensitive systems using DS90CR215MTD/NOPB.
