Zarlink Introduces World’s First Single-Chip Tuner for Free-to-Air Satellite DTV Receivers
ZL10039 (TM) chip combined with high-performance demodulator achieves industry’s most integrated front-end motherboard solution
OTTAWA, CANADAZarlink Semiconductor today introduced the ZL10039 device, the industry’s first single-chip satellite tuner for FTA (free-to-air) satellite DTV receivers. Combined with Zarlink’s ZL10313 satellite demodulator, the ZL10039 direct conversion tuner offers the most integrated and cost-effective front-end solution for the FTA satellite market.
The new tuner includes a high-performance LNA (low-noise amplifier), eliminating the need for additional RF circuitry. Together with the ZL10313 demodulator and supported by the ZLE10541 front-end reference design, satellite STB (set-top box) manufacturers can now achieve the performance required by FTA receivers directly on the motherboard, a cost-effective design approach that has been used in the PayTV market for several years. This design can save over five percent of the total receiver hardware BOM (bill-of-materials) costs.
With the ZL10039 satellite tuner, Zarlink strengthens its leadership position in front-end solutions for digital receivers. Zarlink’s chips are designed into FTA and subscriber-based digital satellite systems worldwide. Satellite was the first digital TV delivery mechanism to achieve worldwide adoption, and still leads in volume, with over 30 million shipments predicted for 2006. Deployments in China and India are continuing to drive demand.
“The advances we have achieved with the ZL10039 tuner and reference design result from our experience serving the high-volume market for free-to-air receivers,” says Bob Ferreira, DTV front-end product line director, Zarlink Semiconductor. “Our tuner with integrated LNA is the first to enable large-scale implementation of FTA front-end designs directly onto the motherboard, saving costs while maintaining performance levels.”
Unlike the PayTV market, where the quality of installation and signal strength is consistently good, the FTA market offers more difficult conditions. The quality of the signal components (dish, cable, connectors) and the installation can be poor, resulting in unacceptable levels of signal attenuation. To address this, and to maximize the number of channels that can be captured, FTA manufacturers typically require receivers with higher performance front-ends, using an external LNA to meet the requirement for additional sensitivity.
For most manufacturers, this added complexity makes an on-board front-end solution unattractive, leading to the selection of a separate and more costly front-end module. The ZL10039 high sensitivity single-chip satellite tuner is the market’s first to resolve this issue.
The ZL10039 device is a single-chip wideband direct conversion tuner for 1 – 45 MSps (megasymbols per second) DVB-S (Digital Video Broadcast-Satellite), DSS (Digital Satellite System), and 8PSK (8-phase shift keying) receiver systems.
Key features include the integrated LNA, an integrated RF loop-through and a “power and forget” VCO (voltage controlled oscillator), eliminating the need for time-consuming VCO calibration required by some competing products.
Zarlink’s ZLE10541 reference design, combining the ZL10039 tuner with the ZL10313 demodulator, offers key features including high speed “blind scan,” which is an on-chip hard-wired controller that enables the chip to achieve ultra-fast channel scanning capability with little intervention from an external processor. The demodulator provides strong performance across the whole satellite 1 – 45 MSps DVB-S symbol rate range.
Zarlink’s two-chip RF subsystem design consumes less than 1 W (watt) of power when in full operation, with an integrated sleep pin that reduces power consumption 1,000-fold in stand-by mode.
The price for the product kit, which includes the ZL10039 and the ZL10313 is $2.88 in quantities of 10,000. The ZL10039 tuner is in full production. The ZLE10541reference design is available to qualified customers. Click here for the data sheet.
