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 co-
processors and corresponding CYV15G0104TRB chips.
The CYV15G0104TRB satisfies the SMPTE 259M and
SMPTE 292M compliance as per SMPTE EG34-1999 Patho-
logical 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.
