Anleitung Zusammenfassung
BiCMOS technology Functional Description The CYV15G0104TRB Independent Clock HOTLink II™ Serializer and Reclocking Deserializer is a point-to-point or point-to-multipoint communications building block enabling transfer of data over a variety of high-speed serial links including SMPTE 292M and SMPTE 259M video applications. It supports signaling rates in the range of 195 to 1500 Mbps per serial link. The transmit and receive channels are independent and can operate simultaneously at different rates. The transmit channel accepts 10-bit parallel characters in an Input Register and converts them to serial data. The receive channel accepts serial data and converts it to 10-bit parallel characters and presents these characters to an Output Register. The received serial data can also be reclocked and retransmitted through the reclocker serial outputs. Figure 1 illustrates typical connections between independent video coprocessors and corresponding CYV15G0104TRB chips. The CYV15G0104TRB satisfies the SMPTE 259M and SMPTE 292M compliance as per SMPTE EG34-1999 Pathological Test Requirements. As a second-generation HOTLink device, the CYV15G0104TRB extends the HOTLink family with enhanced levels of integration and faster data rates, while maintaining serial-link compatibility (data and BIST) with other HOTLink devices. The transmit (TX) channel of the CYV15G0104TRB HOTLink II device accepts scrambled 10-bit transmission characters. These characters are serialized and output from dual Positive ECL (PECL) compatible differential trans- mission-line drivers at a bit-rate of either 10- or 20-times the input reference clock for that channel. The receive (RX) channel of the CYV15G0104TRB HOTLink II device accepts a serial bit-stream from one of two selectable PECL-compatible differential line receivers, and using a completely integrated Clock and Data Recovery PLL, recovers the timing information necessary for data reconstruction. The recovered bit-stream is reclocked and retransmitted through the reclocker serial outputs. Also, the recovered serial data is deserialized and presented to the destination host system. The transmit and receive channels contain an independent BIST pattern generator and checker, respectively. This BIST hardware allows at-speed testing of the high-speed serial data paths in each transmit and receive section, and across the interconnecting links. Figure 1.
