GENERATOR

The MX429A is a single-chip CMOS 1200 and 2400 baud MSK modem, designed primarily for use in Trunked

Radio Systems but may also be employed in other general purpose radio or line data communication

applications. The device has been designed to conform to the UK Band III trunked radio protocols MPT

1317/1327.

The MX429A is full duplex at 1200 and 2400 baud and includes an 8-bit parallel microprocessor interface and

a programmable timer which may be set for interrupt periods of 8 to 120 bits. Preamble may be generated by

the device in transmit. The 16-bit SYNC or SYNT words are detected in receive. An error check word is

automatically generated in transmit and error checking is performed in the receive mode. An on-chip

Xtal/clock generator requiring an external 4.032MHz Xtal or clock input provides both 4.032MHz and

1.008MHz outputs and performs all modem timings.

The MX429A requires a single 5-volt power supply, has a powersave facility, and is available in the following

package styles: 24-pin CDIP (MX429AJ), 24-pin PDIP (MX429AP), and 24-pin PLCC (MX429ALH).
