PEB1756E PEB1756E TETHYS™ 4192 DUAL STS-192/STM-64 MUX/DEMUX FEB 2009 GENERAL DESCRIPTION REV. 1.0.2 • Provides interfaces for dropping alarm and status information, and for forcing alarm conditions Tethys™ 4192 is optimized for SONET/SDH applications as a full-duplex two STS-192/STM-64 MUX/DEMUX with full framer functionality including pointer processing, and overhead termination; ideal for aggregation, ADM and DWDM applications. In the demultiplex ingress direction, Tethys™ 4192 accepts two STS-192/STM-64 signals in SFI-4.1 format. Tethys locates the incoming SONET/SDH frame, optionally descrambles the data, monitors theTOH and POH, and provides STS-1 level pointer processing. In addition, Tethys supports TOH and POH overhead transparency. • Supports system-side input deskew of up to ± 250 ns In the multiplex direction, from the system interface, Tethys™ 4192 accepts two STS-192/STM-64 or eight STS-48/STM-16 signals in either dual 4 x 2.5 Gbit/s or 8 serial 2.5 Gbit/s format. Further Tethys provides corresponding functionality in the DEMUX direction. • Provides full TOH/POH add/drop APPLICATIONS • For diagnostic purposes, Tethys provides PRBS • ADM • Metro Aggregation within a group of 4 x 2.5G GBps for each of two STS-192/ STM-64 • Power dissipation of 15 W, depending on mode of operation • Terminates and generates SONET section, line, and path layers • Provides TOH and POH transparency • Provides monitoring of POH bytes B3 and N1/Z5 • Provides B2 SF/SD capability for Poisson and bursty error distribution • Provides STS-1 level POH add/drop • Supports more than ± 746 UI programmable output skew on STS-192/STM-64 or STS-48/STM-16 out-put links to external cross-connects generator/checker and loop backs • Provides B1, B2, H1 and H2 bit error generation for both receive and transmit direction diagnostics • Digital Cross Connects • Provides 1 second performance monitors • Repeaters • Provides B1, B2, H1 and H2 bit error generation for both • DWDM Equipment receive and transmit direction diagnostics • Test Equipment • Provides 1 second performance monitors FEATURES • 0.13 micron process, 1.2 V core, 3.3 V I/O • Complies with OIF specifications SFI-4.1 • Differential CML 2.5 G I/O interface to system/backplane • TFI-5 Support • Processes SONET/SDH dual STS-192/STM-64 on the line side interface • Processes SONET/SDH dual STS-192/STM-64 or eight STS-48/STM-16 on the system/client side serial 2.5 Gbit/ s interface • Motorola 32-bit synchronous microprocessor inter-face for configuration, control, and status monitoring • Complies with GR-253, GR-1377, ITU-T G.707, and ANSI T1.105 • Provides a standard 5-signal IEEE 1149.1 JTAG test port for boundary scan board test purposes SPECIFICATIONS • OIF SFI-4.1 • Provides line timing of all line and system side interfaces • OIF TFI-5 • Processes SONET/SDH flexible concatenation streams STANDARDS of STS-2c, 3c, 4c, … to 192c • Supports auto-detection of concatenation streams STS3c/STM-1, STS-12c/STM-4, STS-48c/STM-16 and STS192c/STM-64 • Supports STS-1 level pointer processing of STS-192/ STM-64 or STS-48/STM-16 streams • ANSI T1.105-2000-193R2 (DRAFT) • ANSI T1.105.05-1994 • T1X1.3/93-005RI -1993 - preliminary • GR-253-CORE Sept. 2000 • ITU-T G.707 10/2000 Exar Corporation 48720 Kato Road, Fremont CA, 94538 • (510) 668-7000 • FAX (510) 668-7017 • www.exar.com PEB1756E PEB1756E TETHYS™ 4192 DUAL STS-192/STM-64 MUX/DEMUX REV. 1.0.2 ORDERING INFORMATION PART NUMBER PACKAGE OPERATING TEMPERATURE RANGE PEB1756E 1397 CBGA -40°C to +85°C FIGURE 1.
