MICROCHIP COM5016ATT

The Standard Microsystems COM 5016/COM 5036 Dual Baud Rate Generator/Programmable Divider is an N-channel COPLAMOS MOS/LSI device which, from a single crystal (on-chip oscillator) or input frequency is capable of generating 32 externally selectable frequencies. The COM5016/COM5036 is specifically dedicated to generating the full spectrum of 16 asynchronous/synchronous data communication frequencies. One of the sixteen output frequencies is externally selected by four address inputs on each of the independent dividers. Internal re-programmable RoM allows the generation of other frequencies from other crystal frequencies or input frequencies. The four address inputs on each divider section may be strobe (150ns) or DC loaded. As the COM5016/COM 5036 is a dual baud rate generator full duplex (independent receive and transmit frequencies) operation is possible. The COM 5016/COM 5036 is basically a programmable 15-stage feedback shift register capable of dividing any modulo up to (2^15 - 1). By using one of the frequency outputs it is possible to generate additional divisions of the master clock frequency by cascading COM5016/COM5036's. The frequency output is fed into the XTAL/EXT input on a subsequent device. In this way one crystal or input frequency may be used to generate numerous output frequencies. The COM5016/COM 5036 can be driven by either an external crystal or TTL logic level inputs; COM 5016T/COM 5036T is driven by TTL logic level inputs only. The COM 5036 provides a high frequency reference output at one-quarter (1/4) the XTAL/EXT input frequency.
