Product Brief CV92/CV34/CV22 Complete Embedded Data Modems F e at u r e s n n n n n Two-chip modem solution: -- CVxx Modem Device in 48-pin TQFP or 100-pin FSBGA (CV92-F100 only) -- CSP1040 DAA in 20-pin ETSSOP Data mode capabilities: -- V.92, V.90, V.34, V.32bis, V.32, V.22bis, V.22. V.21, Bell 212A, Bell 103 -- V.17 and lower fax rates -- V.44, V.42bis, MNP 5 Data Compression -- V.42, MNP 2-4 Error Correction CVxx Modem Device features: -- ARM7TDMS Microcontroller -- DSP1600S Digital Signal Processor -- DAA interface and filters -- Host interface configurable for 8-bit parallel, asynchronous serial or SPI mode -- On-chip PWM speaker driver -- SIO interface for audio codec used in voice and handset applications -- 24.576 MHz crystal or external 27.0 MHz clock The CVxx family of devices is designed to serve embedded applications that require high-speed dial-up data connections. There are several versions available based on modulations and other features. For designs that must support field-upgrade- 2 shows the features supported for the various CSP1040 DAA features: -- Derives power from system for reliable operation on all phone lines -- Digital transformer isolation barrier -- Programmable event detect for caller-ID reception and power ring detection -- Programmable pulse shaping and spark quench -- Programmable dc-impedance termination for country-specific VI templates -- Programmable ac-impedance termination for return loss matching -- Programmable ringer-impedance emulation -- Hardware support for pulse dialing for accurate make/break timing. -- Hardware support for ringing level and frequency qualification for accurate ring detection. -- Line-in-use and remote handset detection -- World-wide caller ID support ability or customized features, a version of the versions. The CVxx devices support RS232 and CV92 device is available in a 100 FSBGA that 8-bit microprocessor interfaces. Additionally, can support external flash ROM.

The layout can be integrated into a larger PCB or built as a separate module with connectors. Figure 1 shows a reference design using the 48-pin CVxx and the CSP1040. This is a 2-layer PCB with components on top- * Actual speeds over U.S. telephone lines vary and are less than 56K due to current FCC regulations and line conditions.
