TDA5235XUMA1

TDA5235XUMA1 is an enhanced sensitivity double-configuration receiver with digital baseband processing. The IC is a low power ASK/FSK receiver for the multiple frequency band like 902-928MHz. Bi-phase modulation schemes, like Manchester, bi-phase mark, bi-phase space and differential Manchester are supported. The chip offers best-in-class sensitivity performance at a very high level of integration and needs only a few external components. Suitable for remote keyless entry systems, remote start applications, tire pressure monitoring, short range radio data transmission, remote control units, cordless alarm systems and remote metering.
