* 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
Description
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. Clock and Data Recovery are provided for the standard operating rates of 155.52 Mbps (OC-3) and 622.08 Mbps (OC-12). The S1221 can also be provisioned to a mix and match OC-3 and OC-12 data streams within the same device. The S1221 can be configured in MII (Media Independent Interface) mode (MII Mode) or in a Non-MII mode. The figure below, System Block Diagram, shows a typical network application.
The S1221 performs SONET/SDH frame detection. AMCC Suggested Interface Devices Congo (S1201) POS/ATM SONET Mapper Nile (S1202) ATM SONET Mapper

The S1221 is divided into four transmitter channels and four receiver channels. The sequence of operations is as follows for each Channel: Transmitter Operations
* 8-bit parallel data input * Parallel-to-serial conversion * Serial data output
Overview
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. The S1221 is divided into four Transceiver modules with each possessing a clock recovery unit. Each of the modules can run at OC-3 or OC-12 data rates, independent of the other modules.
