IRVINE, Calif., Dec. 17, 2014 /PRNewswire/ -- Broadcom
Corporation (NASDAQ: BRCM), a global innovation leader in
semiconductor solutions for wired and wireless communications,
today announced the industry's first high speed 4-level Pulse
Amplitude Modulation (PAM-4) Physical Layer transceivers (PHYs).
The new PAM-4 PHYs enable transmission rates of 40/50 gigabits per
second (Gbps) serially over multiple physical media, including
direct attach cables (DAC) and optical fiber. For more news, visit
Broadcom's Newsroom.
To support the rapid rise in video and data traffic, there is
growing demand for higher speed and more bandwidth over currently
deployed infrastructure. As a result, system OEMs are looking at
ways to optimize 40/100GbE connectivity. Based on PAM-4 technology,
Broadcom's BCM82040 and BCM82004 devices are the first in a line of
40/50/100GbE devices optimized to meet these requirements.
"Our new PAM-4 PHYs provide the ideal solution for OEMs and data
center operators looking for cost and performance optimization,"
said Lorenzo Longo, Broadcom Vice
President and General Manager, Physical Layer Products. "This
latest addition to our product line-up demonstrates our commitment
to pioneering new technology developments such as PAM-4 and further
solidifies our position as the industry leader in wired physical
layer devices."
The 28 nanometer (nm) BCM82040 and BCM82004 PHYs support higher
data throughput over existing low bandwidth channels by
transmitting more bits per symbol. PAM-4 enables the transmission
of 40 Gbps at a baud rate of 20Gbaud, resulting in improved signal
integrity while re-using existing channels for higher data
throughput and enabling the use of lower cost cables and optics.
The PAM4-line code in the new PHYs require half the bandwidth of
Non-Return-to-Zero (NRZ) line code, resulting in higher throughput
and lower total system cost and power consumption.
Both devices are designed to transmit and receive 40/50G data
over two pairs of media versus eight pairs of media using existing
4x10G quad small form-factor pluggable (QSFP) cables. For 40G
optical applications, the BCM82040 reduces the number of optical
components and optical fibers required by a factor of four,
eliminating expensive components and further reducing cost and
power.
Key Features:
- Single 40/50GbE PHY drives 40/50G serial over various
media
- Supports a variety of DAC reaches from multiple suppliers
- Enables SMF/MMF optics and silicon photonics
- Low-power 28 nm CMOS design
- Small 7x7mm package fits within QSFP+ form factor, cable
assembly and optics modules
Availability
Broadcom's PAM-4 PHYs come in two device options. The BCM82040
is optimized for transmitting 40/50 Gbps over optical fiber and the
BCM82004 is optimized for transmitting 40/50 Gbps over direct
attach cable (DAC). Both devices are now sampling.
