is an LSI Logic CoreWare
transceiver technology family
designed for broadband and networking applications for extremely high band-
width CMOS ASICs.
HyperPHY transceiver technology includes a full clock recovery mechanism
that permits the recovery of clock and data from a data stream alone.
Communication on HyperPHY channels is possible over a variety of physical
media, including copper cable and printed circuit board traces with high speed
backplane connectors

Standard HyperPHY represents the fourth generation of a continuing
transceiver technology family. The HyperPHY methodology allows for the con-
struction of transceiver architectures in an ASIC methodology.
The cores consist of a serializer, a de-serializer with clock and data recov-
ery, and a low-jitter PLL. These cores, shown in Figure 1 as TX, RX and PLL,
respectively, are combined into sub-systems per customer specifications. Figure
1 shows a generic full duplex subsystem, with 32 independent receive channels
and 32 independent transmit channels, all serviced by a single PLL.
