PRODUC T BRIEF S122 1 S1221 OC-3/12 SONET/SDH 8-bit Quad Transceiver Features Description • CMOS 0.13 micron technology • Complies with Bellcore and ITU-T specifications for jitter tolerance, jitter transfer, and jitter generation • On-chip high-frequency PLLs for clock generation and clock recovery • Supports Data Rates for 155.52 Mbps (OC-3) and 622.08 Mbps (OC-12) • 8-bit LVCMOS Parallel data path • LVDS or LVPECL differential serial interface • Internal termination of the optic’s LVPECL driver renders a seamless power saving connection • Typical 715 mW power in LVDS I/O mode • Directly compatible with 2.5 V or 3.3 V LVDS, 3.3 V LVPECL (DC and AC) • Frame and Byte Boundary Detection option • 255 PBGA Package,17x17 mm2 with Green/ RoHS compliant lead free option • 1.2 V and 3.3 V/2.5 V supply • Receiver lock detect outputs • Signal detect inputs • Selectable reference frequencies of 19.44, 77.76 or 155.52 MHz • Internal FIFO to decouple transmit clocks • Various diagnostic loopback modes • Quad configuration, mixed OC-3/OC-12 • Built-In Self Test (BIST) Feature • Independent power down of unused channels • Drop-in-replacement for S1213 The S1221 SONET/SDH transceiver is one of the latest additions to the AMCC product family. The S1221 device provides fully integrated serialization/de-serialization capabilities with four independent transceivers. The device performs all necessary parallel-to-serial and serial-to-parallel functions in conformance with the SONET/SDH transmission standards. Applications The S1221 can be used to implement the front end of SONET/SDH equipment which consists primarily of the serial transmit interface and the serial receive interface. The Low Voltage LVDS or LVPECL interfaces guarantee compliance with the bit-error rate requirements of the Telcordia and ITU-T standards. • • • • • • • • • SONET/SDH OC-3/OC-12 SONET/SDH modules SONET/SDH test equipment ATM over SONET/SDH Section repeaters Add Drop Multiplexers (ADM) Broad-band cross-connects Fiber optic terminators Fiber optic test equipment The S1221 performs SONET/SDH frame detection.
