Product details
Overview
GS9064ACTDE3 from Gennum is a multi-rate SDI adaptive cable equalizer IC designed for serial digital video signal restoration over 75Ω coaxial cable. It supports SMPTE 292M (1.485 Gb/s), SMPTE 259M (270 Mb/s), and SMPTE 344M, delivers 750 mVp-p differential output swing, achieves ≤0.25 UI peak-to-peak jitter at 1.485 Gb/s over 140 m of Belden 1694A cable, and operates from a single 3.3 V supply with 265 mW typical power consumption - deployed in broadcast routing switchers and HD/SD-SDI receiver front-ends.
For engineers reviewing the GS9064ACTDE3 datasheet, pinout, applications, or equivalent options, this page provides verified technical context, exact pin functions, real-world jitter and cable-length performance data, functional alternatives with documented differences, and supply-chain support details specific to the GS9064ACTDE3 variant.
Technical Context
The GS9064ACTDE3 implements an analog adaptive equalization architecture with integrated DC restoration and automatic gain control (AGC) using external 1 µF capacitor on AGC+/AGC− pins. Its equalizer path dynamically compensates for frequency-dependent loss in coaxial cable up to 1.485 Gb/s, while maintaining logic threshold integrity via DC restore for SMPTE pathological patterns.
It features dual-mode mute control: voltage-programmable MCLADJ input sets approximate maximum cable length for automatic muting on SMPTE 259M signals, and bidirectional CD/MUTE pin enables manual override or carrier-detect status reporting. CLI analog output provides real-time cable-length estimation up to 360 Mb/s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate Range | 143 Mb/s to 1.485 Gb/s - supports full SD-SDI, ED-SDI, and HD-SDI standards without reconfiguration. |
| Input Impedance | 1.64 kΩ single-ended - matches 75Ω coaxial interface via internal termination network for minimal reflection. |
| Output Swing | 750 mVp-p differential into 50Ω - ensures robust signal margin for downstream PECL-compatible receivers. |
| Jitter Performance | ≤0.25 UI (1.485 Gb/s, 140 m Belden 1694A) - meets SMPTE 292M eye mask requirements after equalization. |
| Power Supply | Single 3.3 V ±5% - eliminates need for dual-rail supplies and simplifies board-level power design. |
| Operating Temp | 0°C to +70°C - validated for commercial broadcast equipment environments including rack-mounted routers. |
| Cable Length Indicator | Analog CLI output (0–2.5 V range) - enables system-level cable diagnostics and auto-calibration in multi-channel SDI systems. |
Pinout & Package
GS9064ACTDE3 is housed in a 16-pin SOIC package (JEDEC MS-012AC, 9.9 mm × 3.9 mm × 1.45 mm), RoHS-compliant and Pb-free, rated for 0°C to +70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CLI) | Analog Output | Cable Length Indicator voltage proportional to input signal attenuation - used for diagnostics and auto-threshold setting up to 360 Mb/s. |
| 4,5 (SDI, SDI) | Differential Input | 75Ω-coax-coupled serial digital input pair - accepts AC-coupled SMPTE-compliant signals with internal 1.8 V bias. |
| 7,8 (AGC+, AGC−) | Passive Filter Node | Connection point for external 1 µF AGC capacitor - sets time constant for adaptive gain loop convergence and stability. |
| 9 (BYPASS) | Digital Control Input | Active-HIGH logic input forcing equalizer and DC restore stages into transparent bypass mode - used for low-speed debugging or legacy signal paths. |
| 10 (MCLADJ) | Analog Threshold Input | Voltage-adjustable mute trigger for SMPTE 259M - sets approximate max cable length before output muting to suppress noise-induced false data. |
| 12,13 (SDO, SDO) | PECL Differential Output | 50Ω-terminated 750 mVp-p output driving downstream receivers - requires external 50Ω termination to ground for proper PECL level compliance. |
| 16 (CD/MUTE) | Bidirectional Control | Carrier detect status output (low = active) and manual mute control input (high = mute) - not functional in BYPASS mode. |
Key Features
| Feature | Design Value |
|---|---|
| Multi-standard adaptive equalization | Single device handles SMPTE 259M (270 Mb/s), SMPTE 344M (540 Mb/s), and SMPTE 292M (1.485 Gb/s) without firmware or configuration - reduces BOM count in mixed-format infrastructure. |
| DC restoration circuitry | Compensates for baseline wander caused by SMPTE pathological test patterns - maintains correct logic threshold alignment independent of AC coupling losses. |
| Programmable cable-length-based muting | MCLADJ pin allows precise adjustment of mute threshold per channel - prevents false outputs from noise or unterminated inputs in broadcast router matrices. |
| Cable Length Indicator (CLI) | Analog voltage output correlates with received signal attenuation - enables real-time cable health monitoring and automated gain calibration across multi-channel SDI systems. |
| Single-supply 3.3 V operation | Eliminates need for negative rails or LDOs - reduces component count and layout complexity in space-constrained broadcast PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SDI adaptive equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GS1524-CTDE3 | Same die, identical electrical specs and pinout - differs only in tape-and-reel packaging (250 pcs vs. GS9064ACTDE3's 2,500 pcs). | No functional difference; suitable for prototyping or low-volume builds where smaller reels are preferred. | Select GS1524-CTDE3 when evaluating or building pre-production units requiring smaller quantity increments. |
| LMH0384SQ/NOPB | TI device with integrated reclocker; higher power (380 mW), supports SMPTE 424M (3 Gb/s); no CLI or MCLADJ functionality. | Used where jitter cleanup beyond equalization is required - e.g., cascaded distribution or long-haul fiber conversion. | Choose LMH0384SQ/NOPB only if reclocking is mandatory and 3 Gb/s support needed; otherwise GS9064ACTDE3 offers lower cost and diagnostic features. |
Compared with GS1524-CTDE3, GS9064ACTDE3 offers identical signal integrity performance but optimized for high-volume production with larger reel size and traceable lot control; versus LMH0384SQ/NOPB, it trades reclocking capability for lower power, built-in cable diagnostics, and simpler power design - making it preferable for cost-sensitive, multi-channel SDI infrastructure where jitter is managed upstream.

FAQ
What is the maximum supported cable length for GS9064ACTDE3 at 1.485 Gb/s?
The GS9064ACTDE3 supports up to 140 meters of Belden 1694A coaxial cable at 1.485 Gb/s while maintaining ≤0.25 UI peak-to-peak jitter and meeting SMPTE 292M eye mask requirements. Performance is validated using the recommended application circuit and 800 mVp-p launch swing from the source driver.
Does GS9064ACTDE3 require external termination resistors on its SDO outputs?
Yes, GS9064ACTDE3 outputs are PECL-compatible and require external 50Ω termination to ground on both SDO pins to establish correct common-mode voltage (VCM ≈ 2.925 V) and achieve the specified 750 mVp-p differential swing. The internal 50Ω pull-ups referenced in the datasheet apply only to input-side biasing, not output termination.
Can GS9064ACTDE3 be used for DVB-ASI signals at 270 Mb/s?
Yes, GS9064ACTDE3 explicitly supports DVB-ASI at 270 Mb/s per its datasheet Key Features section. It delivers the same jitter performance and equalization accuracy as for SMPTE 259M, making it suitable for broadcast contribution links carrying MPEG-TS over coaxial cable.
What is the function of the BYPASS pin on GS9064ACTDE3?
The BYPASS pin on GS9064ACTDE3 is a logic input that, when driven HIGH, disables the adaptive equalizer and DC restore stages, passing the SDI input signal directly to the SDO outputs. This mode is useful for low-data-rate signals with slow rise/fall times or for system-level debug where equalization is unnecessary.
Is GS9064ACTDE3 RoHS compliant and lead-free?
Yes, GS9064ACTDE3 is Pb-free and RoHS compliant per Gennum's ordering information table and datasheet revision history. It uses matte tin plating on leads and conforms to EU Directive 2011/65/EU, with all homogeneous subcomponents meeting RoHS material restrictions.
