STEVAL-CBL014V1,基于 LNBH26L 的雙 LNB
電源和控制 IC 評估板,符合 DiSeqC 1.x 標準。該評估板實現了一個基于 LNBH26L
器件的 DC-DC
轉換器,用于為接收衛星電視信號的碟形
天線內的 LNB 供電。 LNBH26L 是一款按照國際標準提供/連接衛星 LNB 模塊的集成解決方案,為雙
調諧器衛星接收器提供完整的解決方案,并使用很少的外部組件以低成本實現良好的性能。 LNBH26L 評估板包括一個 I2C 總線接口和內部 22 kHz 音調發生器(工廠調整),由 DSQIN 引腳(TTL 兼容)控制,允許立即進行 DiSEqC 數據編碼。完全集成的升壓 DC-DC 轉換器允許使用 8 V 至 16 V 的單輸入電壓電源運行

STEVAL-CBL014V1, Evaluation Board for Dual LNB supply and control IC DiSeqC 1.x compliant based on the LNBH26L. This Evaluation Board implements a DC-DC converter based on the LNBH26L device used to power LNB inside dish antennas which receive satellite TV signals. The LNBH26L is an integrated solution for supplying/interfacing satellite LNB modules in accordance with international standards, offering a complete solution for dual-tuner satellite receivers and good performance at low cost using few external components. The LNBH26L evaluation board includes an I2C bus interface and the internal 22 kHz tone generator (factory trimmed) is controlled by the DSQIN pin (TTL compatible), permitting immediate DiSEqC data encoding. A fully integrated step-up DC-DC converter allows operation with a single input voltage supply source ranging from 8 V to 16 V
