ATA5757C-6DQY-66

RF Transmitter Overview

The ATA5757C-6DQY-66 is a UHF ASK/FSK RF transmitter IC designed for Tire Pressure Monitoring (TPM) applications. It operates at a frequency of 433 MHz with an output power of 6 dBm and supports data rates up to 40 kbps. The device integrates a programmable oscillator, modulator, and PA driver, utilizing a surface-mount TSSOP-10 package. It is engineered for low-power consumption in automotive environments.

RF Transmitter Feature Summary

• Integrated ASK and FSK modulation capabilities for flexible transmission protocols
• Built-in power amplifier driver optimized for direct antenna connection
• Programmable frequency synthesis for precise channel selection
• Designed specifically for compact tire pressure monitoring systems

RF Transmitter Applications

• Tire Pressure Monitoring System (TPMS) transmitters
• Automotive wireless sensor nodes
• Industrial remote control units requiring UHF transmission

RF Transmitter Procurement Notes

Verify the specific suffix -66 against the manufacturer's current datasheet to confirm pinout and packaging dimensions. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected variant matches the required operating temperature range for automotive integration.

RF Transmitter Selection Notes

Select this component when a dedicated UHF transmitter with integrated modulation and PA drive is required for TPMS designs. Compare against the ATA5749C series if additional programmability or different interface options are needed. Consider the TSSOP-10 footprint constraints during PCB layout planning.

RF Transmitter Part Context

This part belongs to the Microchip ATA57xx family of RF transmitters. It complements other models like the ATA5754C and ATA5749C, offering a balance of performance and simplicity for standard TPM applications. The family shares common design principles for low-power wireless communication in harsh automotive environments.

RF Transmitter Replacement Considerations

Check for direct substitutes within the ATA57xx series such as the ATA5754C-6AQY or ATA5749C variants. Verify compatibility regarding frequency bands, modulation types, and package dimensions before substitution.
