SAN DIEGO--(BUSINESS WIRE)--Feb. 23, 2000--
Low Power and High-volume Manufacturability Strongly
Positions AMCC in the Exploding Growth of the OC-192 Market
Applied Micro Circuits Corp. (AMCC) (NASDAQ:AMCC), a leader in
high-bandwidth silicon connectivity solutions for the world's optical
networks, today announced another industry first, a highly integrated
silicon germanium (SiGe) OC-192 solution set ideal for use in
SONET/SDH and dense wave division multiplexing (DWDM) applications.
The first devices to be compliant with the Optical
Internetworking Forum (OIF) -- Physical Layer Group's OIF99.102
standard, the S3091 transmitter interface chip implements all
necessary SONET/SDH serialization and transmission, and the S3092
receiver with clock and data recovery (CDR) performs all SONET/SDH
deserialization.
To provide an easier interface and maximized compatibility, the
S3091 incorporates a FIFO (First in, First Out) to decouple the
internal and external transmit clocks. Drawing from inherent
advantages of next-generation SiGe technology, the two-chip solution
is easily manufactured in high-volume quantities, and combined
utilizes a total of only 4.5W of power.
"Our mission is to enable our customers to easily deploy, in very
high volumes, OC-192 solutions," said Brent Little, vice president of
marketing for AMCC. "The introduction of this solution set is a key
milestone in accomplishing our mission as the OC-192 market rapidly
expands."
Each device is engineered with a dual 3.3V and -5.2V power
supply, and incorporates a low-jitter 16-bit LVDS interface enabling
reduced pin count and guaranteed compliance with the bit-error rate
requirements of Bellcore and ITU-T industry specifications. The
S3091/S3092 are used to implement the front-end of SONET equipment,
which consists of the serial transmit interface and the serial receive
interface.
Also, the solution can be used in conjunction with AMCC's
Missouri and S3062 devices for ADM and FEC capabilities. The S3091
performs the serializing stage in the processing of a transmit SONET
STS-192 bit-serial data stream, converting the 16-bit parallel OC-12
(622.08 Mbps) data stream to a bit-serial format at OC-192 (9.953
Gbps). Conversely, the S3092 provides the first stage of the digital
processing of a receive SONET STS-192 bit-serial stream, by recovering
a synchronous signal from the incoming OC-192 serial NRZ data stream,
and retiming and demultiplexing the serial data into 16 parallel OC-12
lines.
"The S3091 and S3092 address critical system design issues for
our customers by being an easy to use, low power and highly
manufacturable chipset that exceeds industry standards requirements,"
said Ken Prentiss, AMCC's director of marketing for telecom products.
"We're providing an OC-192 off-the-shelf solution that meets the
high-volume and design cycle demands of this high-growth market."
The system timing circuitry of both chips is designed with AMCC's
proven high-frequency Phase Locked Loop (PLL) technology, consisting
of a phase/frequency detector (PFD), a loop filter, and a voltage
controlled oscillator (VCO). The PFD compares the phase relationship
between the VCO output and the serial data input. A loop filter
converts the PFD output into a smooth DC voltage and the DC voltage is
input to the VCO whose frequency is varied by this voltage. Both the
S3091 and S3092 devices can be used with selectable reference
frequencies of 155 MHz or 622.08 MHz reference clock, in support of
existing system clocking schemes.
The S3091 supports line timing (receiver to transmitter) and
contains on-chip clock synthesis components, allowing the use of a
slower external transmit clock reference. The S3092 contains a lock
detect circuit which monitors the frequency and integrity of the
serial data inputs. Under loss of signal (LOS) conditions, the PLL
locks onto the local reference clock to provide a steady output clock.
Pricing and Availability
Samples of both devices are now available to development
partners. Packaged in a high-throughput 148-pin CBGA, the S3091 and
S3092 are each priced at $495 in quantities of 1000.
