TV tuner handles terrestrial digital broadcasting

Alps Electric have developed TV tuners for terrestrial digital broadcasting, dubbed the TDA Series, which are compatible in common casing with both terrestrial digital and analog broadcasting for Europe and North America.
As the industry transitions from analog to terrestrial digital broadcasting, Alps has provided a set product that is compatible with terrestrial broadcasting technology.

The product series carries models that are compatible with both terrestrial digital and analog broadcasting for each area in Europe and North America and models for digital cable TV broadcasting for China, Europe and other countries. All models come in a common casing realized through Alps' RF circuit technology and high-definition mounting technology.

The tuner offers a single casing size of 53mm x 38mm x 13mm, allowing flexibility and compatibility with all broadcasting standards and configurations in Europe, North America and China. Improvements in the airtightness rate of the casing, restrains tuner noise and improves resistance against noise caused by other parts built into the TV set.

According to the company, tuners that are compatible with both terrestrial digital and analog broadcasting for Europe and North America suffer from noise in the tuner, deteriorating the reception quality of the terrestrial analog broadcasting. To overcome this weakness, Alps built the original circuit into the tuner to reduce tuner noise and to realize higher reception quality for the terrestrial analog broadcasting.

Shipment of samples has started this March.
