简 介:CMX823 Programmable Paging-Tone Decoder
The CMX823 can decode any combination of up to 32 different in-band tones from a user-programmed on-chip list, received in any order. With a decode frequency range of 280Hz to 3500Hz and a Signal-to-Noise Ratio of -4dB, this ultra low-power product is ideal for the majority of paging and selective calling applications, offering reliability in even the most hostile of signalling environments. Total Versatility is the thinking behind the design of this multiple-format tone-decoder as, under serial data control, this product has the selectable option of two measurement modes (Fast and Slow) to efficiently facilitate various tone format periods, operating conditions and host Controller requirements. Decode Speed: Employing two user-defined on-chip lists, the CMX823 can store up to 32 tones per list with the ability to rapidly switch between lists to facilitate different toneset formats. Each list can be further subdivided to allow even faster tone recognition. Tone lists can be dynamically uploaded by the host C if required.
