Semtech Corporation GS6150-INTE3Z

Overview

GS6150-INTE3Z from Semtech is a multi-rate 6G UHD-SDI reclocker IC that recovers embedded clock and retimes serial digital video/audio signals across SMPTE ST 2081 (5.94 Gb/s), ST 424 (2.97 Gb/s), ST 292 (1.485 Gb/s), ST 259-C (270 Mb/s), DVB-ASI (270 Mb/s), and MADI (125 Mb/s) standards. It features four differential inputs, two CML outputs, on-chip 100Ω termination, and operates from a single 1.8V supply with 130 mW typical power consumption.

For engineers reviewing the GS6150-INTE3Z datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, real-world signal integrity parameters (e.g., 0.07–0.13 UI_P-P output jitter at 5.94 Gb/s), GPIO-configurable status monitoring, and bypass mode support up to 5940 Mb/s - all critical for broadcast infrastructure, studio routing, and UHD video transport design.

Technical Context

The GS6150-INTE3Z implements a fully integrated PLL-based retiming architecture with programmable loop bandwidth (7 MHz default at 5.94 Gb/s), automatic rate detection across six discrete data rates, and configurable input trace equalization (LOW/HIGH/BYPASS) optimized for PCB loss compensation up to 10 dB at 3 GHz. Its dual CML outputs support independent swing (310–1000 mV_ppd) and de-emphasis settings.

It integrates a 4:1 high-speed input selector controlled via pins (DDI_SEL0/STROBE, DDI_SEL1), SPI register, or strobe-triggered state transition - enabling tight-timing video switching systems. The device supports both referenceless operation and external 27 MHz crystal reference, with automatic detection and cascading buffer capability for multi-device synchronization.

Key Specifications

Pinout & Package

GS6150-INTE3Z is housed in a 48-pin QFN package (6 mm × 6 mm, 0.4 mm pitch) with exposed thermal pad. Pin assignment follows Gennum's standard layout for high-speed SDI reclockers, featuring dedicated differential I/O pairs, decoupled analog/digital power domains, and four configurable GPIOs.

Compared with GS6150-INTE3Z, GS6151-INTE3Z reduces external component count but lacks flexibility in reference sourcing, while LMH0384SQ/NOPB sacrifices input multiplexing and protocol breadth for lower gate count - making GS6150-INTE3Z the optimal choice for broadcast-grade multi-format, multi-input routing systems.

FAQ

What video standards does the GS6150-INTE3Z support?

The GS6150-INTE3Z supports SMPTE ST 2081 (6G UHD-SDI), ST 424 (3G-SDI), ST 292 (HD-SDI), ST 259-C (SD-SDI), EN50083-9 (DVB-ASI), and AES10 (MADI). It automatically detects and locks to any of these rates - 125 Mb/s, 270 Mb/s, 1.485/1.485÷1.001 Gb/s, 2.97/2.97÷1.001 Gb/s, or 5.94/5.94÷1.001 Gb/s - without configuration changes. This makes GS6150-INTE3Z ideal for multi-format broadcast gear where signal sources vary dynamically.

Does GS6150-INTE3Z require an external crystal?

No, GS6150-INTE3Z operates referencelessly by default, using its internal VCO to lock to the embedded clock in the input signal. An external 27 MHz crystal may be connected to XTAL_CLK_IN to reduce lock time - from 50 ms (referenceless) to 20 ms - especially beneficial in MADI-disabled applications. The device auto-detects crystal presence, so no configuration change is needed when adding or removing it. GS6150-INTE3Z remains fully functional without it.

How many differential inputs and outputs does GS6150-INTE3Z have?

GS6150-INTE3Z has four differential serial input pairs (DDI0/DDI0 through DDI3/DDI3) and two differential serial output pairs (DDO0/DDO0 and DDO1/DDO1). Each input is internally terminated to 100 Ω, and each output supports CML signaling with programmable swing (310–1000 mV_ppd) and de-emphasis. The 4:1 input selector allows any one of the four inputs to be routed to either or both outputs - a key capability for video routing systems.

Can GS6150-INTE3Z pass through unsupported data rates?

Yes, GS6150-INTE3Z supports bypass mode for data rates up to 5940 Mb/s. In manual bypass, the signal passes directly from selected input to DDO0 (or DDO1) with no retiming. In automatic bypass, the device enters bypass when not locked - preserving signal continuity during transient loss-of-lock or when presented with non-SMPTE/DVB-ASI/MADI rates. This ensures robust operation in mixed-signal environments where legacy or proprietary protocols may coexist.

What is the power consumption of GS6150-INTE3Z under typical operating conditions?

GS6150-INTE3Z consumes 130 mW typical when operating referencelessly with one output enabled and processing data below 6G rates. Power rises to 150 mW with the second output enabled, and up to 210–280 mW at 6G rates with maximum output swing and de-emphasis. All values assume 1.8 V core supply and 1.2–2.5 V output driver supplies. Sleep mode draws ≤35 mW, and standby mode ≤110 mW - enabling dynamic power management in portable or thermally constrained broadcast gear.
