The CYW15G0403DXB
[1]
operates from 195 to 1540 MBaud,
which includes operation at the OBSAI RP3 datarate of both
1536 MBaud and 768 MBaud.
The CYV15G0403DXB satisfies the SMPTE-259M and
SMPTE-292M compliance as per SMPTE EG34-1999 Patho-
logical Test Requirements.
As
a
second-generation
CYP(V)(W)15G0403DXB extends the HOTLink family with
enhanced levels of integration and faster data rates, while
maintaining serial-link compatibility (data, command, and
BIST) with other HOTLink devices. The transmit (TX) section
of the CYP(V)(W)15G0403DXB Quad HOTLink II consists of
four independent byte-wide channels. Each channel can
accept either 8-bit data characters or preencoded 10-bit trans-
mission characters. Data characters may be passed from the
Transmit Input Register to an integrated 8B/10B Encoder to
improve their serial transmission characteristics. These
encoded characters are then serialized and output from dual
Positive ECL (PECL) compatible differential transmission-line
drivers at a bit-rate of either 10- or 20-times the input reference
clock for that channel.
The receive (RX) section of the CYP(V)(W)15G0403DXB
Quad HOTLink II consists of four independent byte-wide
channels. Each channel accepts a serial bit-stream from one
of two PECL-compatible differential line receivers, and using
a completely integrated Clock and Data Recovery PLL,

device,
the
recovers the timing information necessary for data recon-
struction. Each recovered bit-stream is deserialized and
framed into characters, 8B/10B decoded, and checked for
transmission errors. Recovered decoded characters are then
written to an internal Elasticity Buffer, and presented to the
destination host system.
The integrated 8B/10B encoder/decoder may be bypassed for
systems that present externally encoded or scrambled data at
the parallel interface.
The parallel I/O interface may be configured for numerous
forms of clocking to provide the highest flexibility in system
architecture. In addition to clocking the transmit path with a
local reference clock, the receive interface may also be
configured to present data relative to a recovered clock or to a
local reference clock.
Each transmit and receive channel contains an independent
BIST pattern generator and checker. This BIST hardware
allows at-speed testing of the high-speed serial data paths in
each transmit and receive section, and across the intercon-
necting links.
The CYP(V)(W)15G0403DXB is ideal for port applications
where different data rates and serial interface standards are
necessary for each channel. Some applications include multi-
protocol routers, aggregation equipment, and switches.
