Functional Description
The CYV15G0404RB Independent Clock Quad HOTLink II™
Deserializing Reclocker is a point-to-point or point-to-multi-
point communications building block enabling data transfer
over a variety of high speed serial links including SMPTE 292
and SMPTE 259 video applications. It supports signaling rates
in the range of 195 to 1500 Mbps for each serial link. The four
channels are independent and can simultaneously operate at
different rates. Each 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, "HOTLink II™ System Connections,"
on page 2 illustrates typical connections between independent
video coprocessors and corresponding CYV15G0404RB
Reclocking Deserializer and CYV15G0403TB Serializer chips.
The CYV15G0404RB is SMPTE-259M and SMPTE-292M
compliant according to SMPTE EG34-1999 Pathological Test
Requirements.
As a second generation HOTLink device, the
CYV15G0404RB 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.
Each channel of the CYV15G0404RB Quad 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
device reclocks and retransmits recovered bit-stream through
the reclocker serial outputs. It also deserializes the recovered
serial data and presents it to the destination host system.
Each channel contains an independent BIST pattern checker.
This BIST hardware enables at speed testing of the
high-speed serial data paths in each receive section of this
device, each transmit section of a connected HOTLink II
device, and across the interconnecting links.
The CYV15G0404RB is ideal for SMPTE applications where
different data rates and serial interface standards are
necessary for each channel. Some applications include
multi-format routers, switchers, format converters, SDI
monitors, and camera control units.
