Functional Description
The CYV15G0204RB Independent Clock Dual HOTLink II™
Deserializing Reclocker is a point-to-point or point-to-multi-
point communications building block enabling transfer of data
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 per serial link. The two
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 illustrates typical connections between
independent
video
co-processors
and
corresponding
CYV15G0204RB
Reclocking
Deserializer
and
CYV15G0203TB Serializer chips.
The
CYV15G0204RB
satisfies
the
SMPTE-259M
and
SMPTE-292M compliance as per SMPTE EG34-1999 Patho-
logical Test Requirements.
As
a
second-generation
HOTLink
device,
the
CYV15G0204RB 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 CYV15G0204RB Dual 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.
Each channel contains an independent BIST pattern checker.
This BIST hardware allows 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 CYV15G0204RB 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.
