The CFAX family of devices is designed to serve embedded applications
where a complete FAX subsystem including protocol processing is de-
sired. The CFAX family includes two devices:
� CFAXV34. Supports V.34, V.17, V.29, and
lower FAX rates.
� CFAXV17. Supports V.17, V.29, and lower
FAX rates.
The CFAX devices support RS232 and 8-bit
micro-processor interfaces. Additionally, the
Figure 1. “Pisa” Embedded Modem Module (shown approximately actual size when printed on 8.5” x 11” paper.)
* Actual speeds over U.S. telephone lines vary and are less than 56K due to current FCC regulations and line conditions.
CFAX devices can be configured for operation
on a 4-wire SPI bus.
Figure 1 shows a reference design using the 48-
pin CFAX and the CSP1040. This is a 2-layer PCB
with components on top-side only. The layout
can be integrated into a larger PCB or built as a
separate module with connectors.
