Set-top Boxes
Connectivity Solutions for IPTV and Digital Set-Top Boxes
Set-top boxes (STBs)—whether for IPTV, OTT streaming, or cable broadcast—require reliable network interfaces to ensure uninterrupted video delivery. LINK‑PP offers a complete range of RJ45 magnetic connectors, discrete LAN magnetics, and optical interface compatibility to support Ethernet and fiber connectivity in STB systems. Our solutions are optimized for compact layout, EMI shielding, and high-speed transmission up to 1Gbps.
Set-Top Box Networking Requirements
- High-Speed Ethernet — Smooth streaming demands stable 100M/1G Ethernet with low insertion loss and return loss.
- Electromagnetic Compatibility — STBs often operate near TVs and home electronics, requiring strict EMI suppression.
- Cost & Size Optimization — Consumer electronics demand compact and cost-effective magnetic components.
- Hybrid Uplink Options — Some STBs integrate SFP ports for FTTH/GPON/EPON fiber uplink deployments.
LINK‑PP Connectivity Solutions for Set-Top Boxes
Magnetic RJ45 Connectors
RJ45 MagJack solutions for STBs integrate the Ethernet jack, isolation transformer, and EMI filter into one compact, shielded package. Ideal for:
- 10/100/1000Mbps Ethernet interfaces
- Low-profile design for slim form-factor enclosures
- Automated SMT placement and reflow compatibility
- Optional LED indicators for link/activity status
LAN Magnetics for Integrated PHY Designs
Some STBs embed the Ethernet PHY into their SoC (System-on-Chip). LINK‑PP provides discrete LAN magnetics that offer:
- 1000Vrms isolation voltage between line and device
- High common-mode rejection (≥30dB @ 100MHz)
- Excellent return loss (≥16dB) for stable video streaming
- Compact SMD or DIP packages for system integration
Optical Interface Support
For FTTH-enabled STBs or hybrid broadcast gateways, optical transceiver cages (SFP) allow integration with fiber access networks. LINK‑PP supports:
- Compatibility with 1G GPON/EPON ONU/ONT modules
- Shielded SFP cages for EMI suppression
- Low power and compact footprint for passive cooling
Application Scenarios
LINK‑PP connectivity components are widely integrated into various types of set-top box applications, including:
- IPTV Set-Top Boxes — Connecting to home gateways via Ethernet for streaming live TV and VOD content
- Hybrid Fiber/IP Devices — Combining Ethernet with SFP optical uplinks for FTTH/GPON/EPON deployments
- Cable/Satellite Digital STBs — Featuring Ethernet ports for remote management or firmware updates
- Smart Projection and Game Boxes — Networked entertainment terminals requiring compact, high-reliability connectors
- Smart TVs with Embedded STB Modules — Using RJ45 ports for IP-based content delivery or streaming
In these scenarios, LINK‑PP stands out for its stable performance, minimal EMI emissions, and compatibility with global OEM production standards.
