Additional Details

The ATA5757-6DQY is a UHF RF transmitter that integrates all the necessary functions for transmitting data wirelessly in the 300-450 MHz frequency band. It supports both Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK) modulation schemes. The device features a low-power wake-up timer that allows the system to remain in a sleep mode until an event triggers the transmitter. The integrated Phase-Locked Loop (PLL) synthesizer ensures accurate frequency generation. The crystal oscillator provides a stable reference frequency. The high output power enables reliable communication over a short range. The 3D Quad Flat No-leads (QFN) package allows for compact system design and efficient heat dissipation. This transmitter is designed to meet the stringent requirements of automotive applications and is commonly used in remote keyless entry systems and tire pressure monitoring systems.
