Framer DS3/E3/STS-1 3.3V 144-Pin TE-CSBGA

The DS3151 (single), DS3152 (dual), DS3153 (triple), and DS3154 (quad) line interface units (LIUs) perform the functions necessary for interfacing at the physical layer to DS3, E3, or STS-1 lines. Each LIU has independent receive and transmit paths and a built-in jitter attenuator.

• Single, Dual, Triple, or Quad Integrated Transmitter, Receiver, and Jitter Attenuators for DS3, E3, and STS-1
• Each Port Independently Configurable
• Perform Receive Clock/Data Recovery and Transmit Waveshaping
• Hardware or CPU Bus Configuration Options
• Jitter Attenuators can be Placed in Either the Receive or Transmit Paths
• Interface to 75O Coaxial Cable at Lengths Up to 380m (DS3), 440m (E3), or 360m (STS-1)
• Use 1:2 Transformers on Tx and Rx
• Require Minimal External Components
• Local and Remote Loopbacks
• Low-Power 3.3V Operation (5V Tolerant I/O)
• Industrial Temperature Range: -40°C to +85°C
• Small Package: 144-Pin, 13mm x 13mm Thermally Enhanced CSBGA
• IEEE 1149.1 JTAG Support
