Description
Toshiba’s TC35823F single-chip Quad Physical Layer Controller (QPLC) is ideal for use in multi-port asynchronous transfer mode (ATM) switch applications. Its integrated clock functions eliminate the need for external clock data recovery and help reduce costs and space requirements in ATM applications including switches, hubs, routers, bridges, enterprise and access multiplexers, video servers, file servers and FTTC/FTTH.

FEATUREs
• Four port Quad Physical Layer Controller
• Clock data recovery (CDR) PLL for each port
• Maps ATM cells into SONET or SDH frames
• Each port operates independently at 155.52Mbps (STS-3C and SDH), 51.84Mbps (STS-1) or 25.92Mbps (STS-1/2)
• Generates and detects SONET/SDH path, line and section overhead
• ATM Forum UNI 3.1 and ITU I.432 compliant
• UTOPIA Level 2 Interface
• 240-pin PQFP
• 0.6 micron CMOS, 5 volts

Benefits
• Reduces cost and board space
• Integrated clock functions eliminates need for external clock data recovery
• Maintains data transfer rate with low jitter

APPLICATIONs
• ATM switches and hubs
• Routers and bridges
• Enterprise and access multiplexers
• Video and file servers
• FTTC/FTTH
