Functional Description
The CYP15G0101DXB[1] single-channel HOTLink II™
transceiver is a point-to-point communications building block
allowing the transfer of data over a high-speed serial link (optical
fiber, balanced, and unbalanced copper transmission lines) at
signaling speeds ranging from 195 to 1500 MBaud.
The transmit channel accepts parallel characters in an input
register, encodes each character for transport, and converts it to
serial data. The receive channel accepts serial data and converts
it to parallel data, frames the data to character boundaries,
decodes the framed characters into data and special characters,
and presents these characters to an output register. Figure 1
illustrates typical connections between independent host
systems and corresponding CYP(V)15G0101DXB parts. As a
second-generation HOTLink device, the CYP(V)15G0101DXB
extends the HOTLink II family with enhanced levels of
integration and faster data rates, while maintaining serial-link
compatibility (data, command, and BIST) with other HOTLink

1. CYV15G0101DXB refers to SMPTE 259M and SMPTE 292M compliant devices. CYP15G0101DXB refers to devices not compliant to SMPTE 259M and SMPTE
292M pathological test requirements. CYP(V)15G0101DXB refers both devices.

The CYV15G0101DXB satisfies the SMPTE 259M and SMPTE
292M compliance as per the EG34-1999 pathological test
requirements. The transmit (TX) section of the
CYP(V)15G0101DXB single-channel HOTLink II consists of a
byte-wide channel. The channel can accept either eight-bit data
characters or pre-encoded 10-bit transmission characters. Data
characters are passed from the transmit input register to an
embedded 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.
The receive (RX) section of the CYP(V)15G0101DXB
single-channel HOTLink II consists of a byte-wide channel. The
channel accepts a serial bit-stream from one of two
PECL-compatible differential line receivers and, using a
completely integrated PLL clock synchronizer, recovers the
timing information necessary for data reconstruction. The
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 interfaces
from one or multiple sources, the receive interface may be
configured to present data relative to a recovered clock or to a
local reference clock.
The transmit and the receive channels contain BIST pattern
generators and checkers, respectively. This BIST hardware
allows at-speed testing of the high-speed serial data paths in
both transmit and receive sections, as well as across the
interconnecting links.
HOTLink II devices are ideal for a variety of applications where
parallel interfaces can be replaced with high-speed,
point-to-point serial links. Some applications include
interconnecting backplanes on switches, routers, base-stations,
servers and video transmission systems.
The CYV15G0101DXB is verified by testing to be compliant to
all the pathological test patterns documented in SMPTE
EG34-1999, for both the SMPTE 259M and 292M signaling
rates. The tests ensure that the receiver recovers data with no
errors for the following patterns:
1. Repetitions of 20 ones and 20 zeros.
2. Single burst of 44 ones or 44 zeros.
3. Repetitions of 19 ones followed by 1 zero or 19 zeros followed
by 1 one.
