Low Power Super-heterodyne OOK/ASK Receiver TDH9903 Datasheet DESCRIPTION The TDH9903 is a low power super-heterodyne OOK/ASK receiver for the 315/434 MHz frequency bands. It offers a high level of integration and requires only few external components. The PT4303 consists of a low-noise amplifier (LNA), a down-conversion mixer, an on-chip phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO) and loop filter, an OOK/ASK demodulator, a data filter, a data slicing comparator and an on-chip regulator. The TDH9903 is available in 4-pin SOP package and is specified over the extended temperature range (-40 to +85°C).
