FUNCTIONAL DESCRIPTION
The 3D7523 is a monolithic CMOS Manchester Encoder/Decoder combo chip. The device uses bi-phase-level encoding to embed a clock signal into a data stream for transmission across a communications link. In this encoding mode, a logic one is represented by a high-to-low transition in the center of the bit cell, while a logic zero is represented by a low-to-high transition.

FEATURES
• All-silicon, low-power CMOS technology
• Encoder and decoder function independently
• Encoder has buffered clock output
• TTL/CMOS compatible inputs and outputs
• Vapor phase, IR and wave solderable
• Auto-insertable (DIP pkg.)
• Low ground bounce noise
• Maximum data rate: 50 MBaud
• Data rate range: ±15%
• Lock-in time: 1 bit
