MITSUBISHI SEMICONDUCTOR CMOS> Preliminary M69897VP 16:1 2.488 Gbps Multiplexer DESCRIPTION The M69897VP multiplexer chip is an integrated serialization SONET OC-48 (2.488 Gbps) interface device. The chip performs parallel-to-serial functions in conformance with SONET/SDH transmission standards. The device is suitable for SONET-based ATM applications. The merits of SOI (Silicon-On-Insulator) technology, such as low voltage operation, low substrate noise and good compatibility with standard CMOS technology, are fully utilized in the chip design to achieve low jitter and low power operation and small package outline of 64-pin PQFP. FEATURES - Single 1.8 V power supply - Supports 2.488 Gbps (OC-48, STM-16) - 16-bit single-ended PECL interface - On-chip high-frequency PLL for clock generation - 155.52 MHz reference frequency - Low power consumption - Available in 64 PQFP - Parity check function APPLICATIONS - SONET/SDH systems - Fiber optic systems - High-speed back plane interconnect and point-to-point data links PARITY PARITYI PARIERRO CHECK 16 PDI[15:0] 155.52 Mbps 16:1 PARALLEL D-FF TO SERIAL 2 SDOP/SDON 2.488 Gbps 2 PCLKOP/ PCLKON 2 TIMING 155.52 MHz 2 2.488 GHz 2.488 GHz GENERATOR 2.488 GHz SCLKOP/ SCLKON SCLKIP/ SCLKIN 2.488 GHz PCLKIP/ PCLKIN 2 2 155.52 MHz PLL LPF_EXT1/ LPF_EXT2 SELPLL Figure 1 Functional Block Diagram 1 MITSUBISHI ELECTRIC December 2000 Table 1 Absolute Maximum Ratings PARAMETER Storage Temperature Voltage on V DD with Resp...
