The SM8213AM is a POCSAG-standard (Post Office Code Standardization Advisory Group) signal processor LSI, which conforms to CCIR recommendation 584 concerning standard international wireless calling codes. The SM8213AM supports call messages in either tone, numerical or character outputs at signal speeds of 512, 1200 or 2400 bps. The signal input stage features a built-in filter. Each of the addresses (max. 7 + 1 dummy = 8) can be assigned to any frame, which also makes the device configurable for many additional services. Each address can be independently set to ON/OFF.
