SAN/WAN Applications (CDR)

1 Description
The QT2032 and QT2022 products are fully integrated PHY ICs designed for use in 10 Gb/s IEEE 802.3-2005
compliant Ethernet and Fibre Channel LAN, SAN and WAN applications. The main physical layer functions (PHY)
of the receiver and transmitter are integrated onto a single chip.
The QT2022 is a serial to XAUI bidirectional PHY chip that integrates the XGXS, PCS and PMA layers and sup-
ports 10 Gb/s Ethernet (10GBASE-R) and 10 Gb/s Fibre Channel protocols. In addition to the QT2022 features,
the QT2032 includes an IEEE802.3-2005 WAN Interface Sublayer (WIS) for Ethernet over SONET protocol
(10GBASE-W). This layer can be bypassed for LAN or SAN applications.
In the transmit direction, the chip converts four differential input 3.125 Gb/s lanes (XAUI) into a serial 9.95-10.5 Gb/
s data stream. In the receive direction the chip converts an input serial 9.95-10.5 Gb/s data stream into four differ-
ential output 3.125 Gb/s lanes (XAUI).
The QT2032 and QT2022 include a standard two-wire interface for communicating with external EEPROM and
DOM devices or XFP modules. An MDC/MDIO interface provides control and status capability for the IC.
In the QT2032, maximum flexibility is provided by the transmit data clocking and jitter clean-up options and
extended SONET overhead processing when connecting the module to the existing OC-192 and DWDM networks.
The QT2032 and QT2022 are fully compliant with IEEE 802.3-2005 10GE and ANSI INCITS/T11 10GFC stan-
dards, and the XENPAK, XPAK, X2, and XFP Multi Source Agreements (MSA).
