Intersil today announced an aggressive new expansion into video applications with three new products to speed video transmission over coaxial and CAT 5 cabling.
The Intersil Techwell Security Link over Coax (SLOC) devices are composed of the TW3801 camera modem PHY and the TW3811 receiver modem PHY . The SLOC devices are a new product family for Intersil, coming in the wake of the company’s springtime acquisition of Techwell , a fabless company mixed-signal video IC provider (including quad muxes, quad decoders and PCI/PCIe decoders).
The second product thrust is the Intersil MegaQ adaptive composite video equalizer , the ISL59601/2/3/4/5.
SLOC modems
The SLOC modem solution is designed to simultaneously transmit analog CVBS (Composite Video, Blanking, and Sync) video and digital IP video over a single coaxial cable. The benefit of the solution is to enable companies to install newer, megapixel ip cameras without having to replace or modify their existing coax infrastructure .
Since the solution allows for latency-free viewing and controlling of cameras, system makers can build systems that support both latency-free closed-circuit TV and networked ip surveillance.
Key features of the TW3801 camera modem phy :
- Simultaneous transmission of analog CVBS video & digital IP data over along coaxial cable (up to 500m)
- Integrated PLL with 25MHz XTAL
- 1.8V, 3.3V supply
- Full-duplex digital communications
- Downlink throughput up to 36Mbps (from camera to receiver)
- Uplink throughput up to 11Mbps (from receiver to camera)
- Ethernet MAC MII interface for interfacing to camera processor DSP/SoC
- Optional Ethernet PHY MII interface for interfacing to external Ethernet PHY chip
- 2-wire control interface
Key features of the TW3811 receiver modem phy :
- Simultaneous transmission of analog CVBS video & digital IP data over a long coaxial cable (up to 500m)
- Full-duplex digital communications
- Downlink throughput up to 36Mbps (from camera to receiver)
- Uplink throughput up to 11Mbps (from receiver to camera)
- Downlink throughput up to 36Mbps (from camera to receiver)
- Proprietary SLOC-based IP camera detection
- Ethernet MAC MII interface for interfacing to DVR/NVR network processor SoC
- 2-wire control interface
- Integrated PLL with 25MHz XTAL interface
- 1.8V, 3.3V supply
Availability : TW3801 and the TW3811 are available in engineering samples in the 100-TQFP (12x12mm) package. Mass production samples are slated for Q1 2011 .
Pricing : $35 each in 1,000-piece quantities.

MegaQ
The MegaQ device family is designed to automatically equalize video over both Cat 5 and xoax and deliver excellent video quality at distances of 1 mile , or five times the distances currently possible.
This achievement eliminates the current need for repeaters and distribution hubs along broad swaths of cabling. The ISL59605 compensates for high-frequency cable loss up to 60dB at 5MHz and source amplitude variations up to ±3dB.
Key features :
- Receive-side-only solution
- Single-chip solution for fully automatic equalization
- Continuous mode adjusts for any variations in the system (such as temperature)
- Equalizers require a single +5V supply and consume 500mW
- Monitors and compensates for long-term cable degradation
Availability : The ISL59601, ISL59602, ISL56903, ISL59604, and ISL59605 are sampling now in compact 4×4 20-lead QFN packages.
Pricing :
