Preliminary
MITSUBISHI SEMICONDUCTOR <SOI/CMOS>
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
