The CVxx family of devices is designed to serve embedded applications

that require high-speed dial-up data connections. There are several ver-

sions available based on modulations and other features.

For designs that must support field-upgrade-

ability or customized features, a version of the

CV92 device is available in a 100 FSBGA that

can support external flash ROM. All other ver-

sions run from on-chip ROM. The table on page

Figure 1 shows a reference design using the 48-pin CVxx 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.

* Actual speeds over U.S. telephone lines vary and are less than 56K due to current FCC regulations and line conditions.

2 shows the features supported for the various

versions. The CVxx devices support RS232 and

8-bit microprocessor interfaces. Additionally,

the CVxx devices can be configured for opera-

tion on a 4-wire SPI bus.
