Maxim Integrated Products introduces the MAX7057 crystal-referenced, phased-locked loop (PLL) VHF/UHF transmitter for transmitting OOK/ASK/FSK data over a wide range of frequencies. This device can operate at any frequency in the 300MHz to 450MHz range with the proper crystal frequency, and it can transmit data at up to 100kbps NRZ (50kbps Manchester coded). |

Maxim Integrated Products introduces the MAX7058 crystal-referenced, phased-locked loop (PLL) VHF/UHF transmitter for transmitting OOK/ASK/FSK data at 315MHz or 390MHz. This device supports 315MHz/390MHz switched operation with a single 15MHz crystal, and can operate at any two frequencies in the 300MHz to 450MHz range with the use of different crystal frequencies. |
