Product details
Overview
SN65LVDS315 from Texas Instruments is a camera serializer IC that converts 8-bit parallel RGB camera data and sync signals (VS/HS) into MIPI CSI-1–compliant SubLVDS serial output, supporting pixel clock frequencies from 3.5 MHz to 27 MHz, operating at 1.8 V core supply, and delivering differential outputs (DOUT±, CLK±) with 100–250 mV differential swing for direct interface to OMAP CSI receivers.
For engineers reviewing the SN65LVDS315 datasheet, SN65LVDS315 pinout, SN65LVDS315 application, or SN65LVDS315 equivalent, this device is selected for mobile camera modules requiring low-power parallel-to-serial conversion, precise frame/line synchronization handling, ESD-hardened inputs (>3 kV HBM on camera ports), and compatibility with TI's OMAP2420/2430/3430 host processors.
Technical Context
The SN65LVDS315 implements an integrated PLL that multiplies the DCLK input by 8× to generate the SubLVDS serial clock (CLK±), while latching all 8-bit pixel data, VS, and HS on the falling edge of DCLK. Its functional block includes line-count logic (enabled via MODE pin), glitch-suppressed TXEN control, and bus-hold inputs for robust camera interface.
It supports three power states: active mode (7 mA typical at VGA 30 fps), standby (<10 μA), and shutdown (<0.5 μA), with automatic standby detection triggered by DCLK <500 kHz. Input voltage tolerance spans 1.65–3.6 V for D[0:7]/VS/HS/DCLK (VDDIO-referenced), while VDDD and VDDA are fixed at 1.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pixel Clock Range | 3.5–27 MHz - defines supported camera sensor resolutions and frame rates (e.g., VGA @ 11 MHz, QVGA @ 6.5 MHz) |
| Differential Output Swing | 100–250 mV - ensures reliable signal integrity over FR4 PCB traces up to 80 inches at 208 Mbps |
| Supply Voltages | VDDIO = 1.65–3.6 V; VDDD/VDDA = 1.65–1.95 V - enables flexible I/O interfacing while maintaining 1.8 V core logic |
| Power Consumption | 7 mA active (VGA 30 fps); 0.5 μA shutdown - enables battery-sensitive mobile camera systems |
| ESD Rating | >3 kV HBM on camera inputs (D[0:7], VS, HS, DCLK); >2 kV HBM on all other pins - protects against assembly and handling stress |
| Operating Temperature | –40°C to +85°C - qualified for automotive cabin and industrial handheld camera environments |
| Output Jitter | 5 ps-rms period jitter (DCLK input); cycle-to-cycle jitter ≤140 ps at 26 MHz - preserves timing margin for MIPI CSI-1 receiver sampling |
Pinout & Package
SN65LVDS315 is housed in a 24-pin VQFN package (4.00 mm × 4.00 mm, 0.5-mm pitch) with wettable flanks, optimized for space-constrained mobile camera modules and thermally efficient PCB layout using a single ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D0–D7 | CMOS camera data inputs | Latched on falling DCLK edge; support 1.65–3.6 V logic; include bus-hold for floating-input immunity |
| VS / HS | Frame/line sync inputs | Sampled on every falling DCLK edge; high-active; bus-hold enabled; used to generate SOF/EOF/SOL/EOL packets |
| DCLK | Camera pixel clock input | Falling-edge sampled; frequency determines serial bit rate (×8 PLL); auto-detects standby below 500 kHz |
| TXEN | Transmitter enable control | CMOS input with 10 μs glitch suppression; high = active transmission; low = shutdown (PLL off, outputs Hi-Z) |
| MODE | Line counter enable | High = enables internal line counter for EOF generation when VS/HS misalign; prevents frame sync loss |
| FSEL | Frequency select | Low = 3.5–13 MHz DCLK range; High = 7–27 MHz DCLK range; sets PLL loop bandwidth and timing margins |
| DOUT+/DOUT− CLK+/CLK− |
SubLVDS serial outputs | MIPI CSI-1 Mode 0 compliant; 100–250 mV differential swing; 0.8–1.0 V common-mode; 5 kΩ differential impedance |
| VDDIO / VDDD / VDDA | Supply rails | VDDIO powers I/Os (1.65–3.6 V); VDDD (1.8 V) powers digital logic; VDDA (1.8 V) powers PLL/SubLVDS analog circuitry |
| GNDD / GNDA | Ground terminals | Separate digital (GNDD) and analog/PLL (GNDA) grounds - require dedicated vias to common PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| MIPI CSI-1 and SMIA CCP compliance | Generates standard SOF/EOF/SOL/EOL packet headers and video data payloads compatible with OMAP CSI receivers |
| Direct OMAP CSI interface support | Optimized setup/hold timing and SubLVDS electrical specs eliminate need for external level shifters or retimers |
| Three low-power operating modes | Active (7 mA), standby (<10 μA), shutdown (<0.5 μA) - controlled via TXEN and auto-detected DCLK frequency |
| Robust input protection | Bus-hold on all CMOS inputs prevents floating states; failsafe power-up behavior avoids current injection during sequencing |
| Flexible I/O voltage range | VDDIO supports 1.65–3.6 V - allows direct connection to 1.8 V or 3.3 V camera sensors without level translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar camera serializer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65LVDS314RGER | Single-channel version (no VS/HS support); only D[0:7] + DCLK → DOUT±/CLK±; no line/frame sync generation | Suitable for non-camera applications like display data serialization where sync signals are absent | Select SN65LVDS314 only if frame/line synchronization is handled externally or unnecessary |
| MAX9250GTJ+T | GMSL-compatible serializer; supports longer cable reach (15 m), higher data rate (1.5 Gbps), but requires MAX9251 deserializer | Targeted at automotive ADAS cameras with coaxial cable and ECU integration, not mobile phone PCB-level use | Choose MAX9250 only when long-distance, noise-immune cabling and GMSL ecosystem alignment are required |
Compared with SN65LVDS315, SN65LVDS314 lacks VS/HS processing and frame control logic, making it unsuitable for camera applications requiring MIPI CSI-1 packetization; MAX9250 targets automotive GMSL infrastructure and introduces system-level complexity incompatible with OMAP-based mobile designs.

FAQ
What is the primary function of the SN65LVDS315?
The SN65LVDS315 is a dedicated camera serializer IC that converts 8-bit parallel RGB pixel data and vertical/horizontal sync signals (VS/HS) into a MIPI CSI-1–compliant SubLVDS serial stream. It performs critical functions including 8× PLL clock multiplication, SOF/EOF packet generation, line counting (via MODE pin), and low-power mode management - all essential for interfacing CMOS image sensors with OMAP processors. The SN65LVDS315 handles timing-critical serialization without external logic.
Does the SN65LVDS315 support both MIPI CSI-1 and SMIA CCP standards?
Yes, the SN65LVDS315 explicitly supports both MIPI CSI-1 and SMIA CCP protocols as stated in its official features and functional description. It generates standard synchronization codes (SOF, EOF, SOL, EOL) and formats serialized video data to comply with either specification, enabling interoperability with host processors and image sensors certified for either standard. This dual support is intrinsic to the SN65LVDS315's packet engine architecture and is validated across its recommended operating conditions.
How does the FSEL pin affect SN65LVDS315 operation?
The FSEL pin selects the DCLK input frequency range: FSEL = 0 enables 3.5–13 MHz operation, while FSEL = 1 enables 7–27 MHz. This setting adjusts the PLL loop bandwidth and internal timing margins to maintain signal integrity and jitter performance across the full pixel clock range. Leaving FSEL floating is prohibited; it must be hard-wired high or low. The SN65LVDS315 datasheet specifies distinct switching characteristics and power consumption values for each FSEL state, confirming its role as a critical configuration input for the SN65LVDS315.
What power-saving modes does the SN65LVDS315 provide?
The SN65LVDS315 offers three hardware-controlled power modes: active (7 mA typical at VGA 30 fps), standby (<10 μA, triggered automatically when DCLK falls below 500 kHz), and shutdown (<0.5 μA, activated by pulling TXEN low). All modes retain register state and allow fast wake-up: standby resumes in <100 μs + 2×VS↑, shutdown enables full transmission in <100 μs + 100 μs after TXEN assertion. These modes are integral to the SN65LVDS315's design for battery-powered mobile cameras.
Can the SN65LVDS315 interface directly with a 3.3 V camera sensor?
Yes, the SN65LVDS315 supports VDDIO from 1.65 V to 3.6 V, allowing direct connection to 3.3 V CMOS image sensors on its D[0:7], VS, HS, and DCLK inputs. Its input thresholds (VIH = 0.7×VDDIO, VIL = 0.3×VDDIO) and bus-hold circuitry ensure reliable logic-level recognition and floating-input immunity. This VDDIO flexibility eliminates level shifters in mixed-voltage camera subsystems - a key design advantage built into the SN65LVDS315's I/O architecture.
