Product details
Overview
LM2512ASN/NOPB from Texas Instruments is a Mobile Pixel Link (MPL-1) Serializer IC that converts 24-bit RGB + VS/HS/DE video signals into a 2- or 3-lane MPL serial stream. It supports up to 640×480 VGA at 22.5 MHz PCLK, performs optional 24-to-18-bit stochastic dithering, and integrates a three-channel 256×8-bit LUT for independent color correction. It operates with 1.6–2.0 V core/analog supply and 1.6–3.0 V I/O supply.
For engineers reviewing the LM2512ASN/NOPB datasheet, LM2512ASN/NOPB pinout, LM2512ASN/NOPB application, or LM2512ASN/NOPB equivalent, key selection criteria include MPL-1 physical layer compliance, dithering algorithm fidelity, SPI-configurable lane count (2 vs 3 MD), LUT enable/disable behavior across power-down cycles, and current-mode MPL driver output specifications (IB = 190 µA, IOLL/IOLH ratios).
Technical Context
The LM2512ASN/NOPB implements an MPL Level 0 Enhanced Protocol with Class 0 PHY, using single-ended current-mode signaling on MD[2:0] and MC lines. Its PLL locks to PCLK (5–22.5 MHz), generating an 80 MHz MC clock at 20 MHz PCLK in 3-lane mode, enabling 160 Mbps per MD lane (480 Mbps raw throughput).
It features dual-phase startup: bias block activation (t₀ = 200 PCLK cycles), followed by MC-driven link-up sequence (t₁–t₄) including current-level calibration and PLL lock (600-cycle hold-off). Frame synchronization uses auto-resync via F[1:0] incrementing bits embedded in every pixel payload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PCLK Range | 5–22.5 MHz (supports QVGA to VGA; 3-lane: 7.5–22.5 MHz, 2-lane: 5–15 MHz) |
| MPL Output Type | Single-ended current-mode drivers (IB = 190 µA; IOLL = 5×IB, IOLH = 1×IB) |
| Dither Resolution | 24-bit → 18-bit stochastic dither with blue-noise characteristic; requires VS input |
| LUT Capacity | Three independent 256×8-bit SRAMs (Red/Green/Blue); disabled by default and after PD* cycle |
| Supply Voltages | VDD/VDDA: 1.6–2.0 V; VDDIO: 1.6–3.0 V; enables level translation between host and display |
| Power-Down Current | <5 µA total (VDD/VDDA + VDDIO) when PD* = L or PCLK stopped |
| SPI Interface | 3-wire (CSX/SCL/SDA); supports 16-bit WRITE/READ and PAGE WRITE; requires REG22 unlock |
Pinout & Package
LM2512ASN/NOPB is packaged in a 40-pin QFN (NJM0040A) with 0.5 mm pitch and exposed thermal pad (VSSIO). Pin functions are validated per TI SNLS269B Rev. May 2013.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| R[7:0], G[7:0], B[7:0] | Parallel RGB data inputs | 24-bit LVCMOS video bus; latched on PCLK rising edge; MSB-aligned for dither bypass |
| VS, HS, DE, PCLK | Video timing control inputs | LVCMOS synchronous interface; VS required for dither frame alignment; DE polarity configurable via register |
| MD[2:0], MC | MPL serial output drivers | Current-mode outputs (3 MD lanes + clock); support 2-lane (default) or 3-lane configuration via SPI |
| SPI_CSX, SPI_SCL, SPI_SDA/HS | SPI configuration interface | Multi-function: SDA doubles as HS input when CSX high; SPI disabled during PD* = L or PCLK stop |
| PD* | Active-high enable input | Drives SER into sleep mode (<5 µA) when low; resets registers but retains LUT data |
| VDDA, VDD, VDDIO, VSSA, VSS, VSSIO | Power and ground rails | Separate analog (VDDA/VSSA), core (VDD/VSS), and I/O (VDDIO/VSSIO) domains for noise isolation |
Key Features
| Feature | Design Value |
|---|---|
| 24-bit to 18-bit dithering | Stochastic "blue noise" algorithm minimizes visible patterning; frame-aligned using VS signal |
| Configurable MPL lane count | SPI-selectable 2-lane (default) or 3-lane operation; adjusts raw throughput from 320 to 480 Mbps |
| Independent color correction | Three 256×8-bit LUTs (R/G/B) loaded via SPI; retained across PD* cycles but lost on full power loss |
| Intrinsic level translation | Accepts 1.6–3.0 V LVCMOS inputs while driving MPL current-mode outputs referenced to 1.6–2.0 V |
| Auto-resync frame sequencing | F[1:0] bits auto-increment per pixel; enables deserializer to detect and recover from sync loss without overhead coding |
| Low-power link management | Power-down current <5 µA; supports STOP-PCLK auto-power-down and PD*-controlled sleep entry/exit |
Applications
| Mobile Display Interconnect | VGA Resolution Video Bridge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar MPL serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2511ASN/NOPB | No dithering engine; no LUT; fixed 2-lane MPL only; lower ICC (4.1 mA typical) | Suitable only for 18-bit-native sources; lacks color correction and frame-sync resiliency | Select when cost and power are critical and dithering/LUT are unnecessary |
| DS90C124MTD/NOPB | FPD-Link II serializer (not MPL); 24-bit RGB + control; LVDS outputs; higher voltage (3.3 V) | Requires matched-pair differential routing; incompatible with MPL deserializers like FPD95320 | Choose only when migrating existing FPD-Link II infrastructure; not drop-in for MPL systems |
Compared with LM2512ASN/NOPB, LM2511ASN/NOPB removes dithering and LUT to reduce cost and active current, while DS90C124MTD/NOPB replaces MPL's current-mode simplicity with LVDS complexity and higher system-level routing demands.

FAQ
What is the maximum PCLK frequency supported by the LM2512ASN/NOPB in 3-lane mode?
The LM2512ASN/NOPB supports up to 22.5 MHz PCLK in 3-lane mode, enabling full 640×480 VGA at 60 Hz. At this rate, the internal PLL generates an 80 MHz MC clock, delivering 160 Mbps per MD lane for 480 Mbps raw throughput. Operation above 22.5 MHz violates the recommended operating conditions and risks timing violations in the dither block and MPL serialization logic.
Does the LM2512ASN/NOPB retain LUT data during power-down mode?
Yes, the LM2512ASN/NOPB retains LUT SRAM contents when entering power-down mode via PD* = L or PCLK stop. However, LUT functionality remains disabled until explicitly re-enabled via SPI register write (REG0 = 01h) after wake-up. Full power cycling (VDD/VDDA removal) clears LUT data, requiring reload before use.
Can the LM2512ASN/NOPB operate with a 1.2 V I/O supply?
No, the LM2512ASN/NOPB requires VDDIO between 1.6 V and 3.0 V per its absolute maximum and recommended operating conditions. A 1.2 V supply falls outside specification and will result in undefined LVCMOS input thresholds (VIH/VIL), unreliable SPI communication, and potential failure of the R/G/B input buffers. Minimum valid VDDIO is 1.6 V.
How does the LM2512ASN/NOPB handle synchronization loss on the MPL link?
The LM2512ASN/NOPB embeds auto-incrementing F[1:0] frame sequence bits in every pixel payload. When synchronization is lost, the companion deserializer detects the repeating 2-bit pattern and realigns the data stream without protocol overhead or pixel expansion. This method adds only 3/24 = 12.5% overhead per pixel and requires no host intervention.
Is the LM2512ASN/NOPB pin-compatible with the LM2512A without the /NOPB suffix?
Yes, LM2512ASN/NOPB is the RoHS-compliant, lead-free packaging variant of the LM2512A. Both share identical pinout, electrical characteristics, timing, and functional behavior. The /NOPB suffix denotes green packaging (Pb-free, halogen-free) and does not affect circuit design, layout, or firmware compatibility.
