Atmel T5744
The T5744 is a PLL receiver device for the receiving range of f 0 = 300 MHz to 450 MHz. It is developed for the demands of RF low-cost data communication systems with low data rates and fits for most types of modulation schemes including Manchester, Biphase and most PWM protocols. Its main applications are in the areas of telemetering, security technology and keyless-entry systems.| Part No. | T5744 |
