AS1161-BCCT

Overview

The AS1160 is a serializer and the AS1161 is a deserializer designed for high-speed data transmission. They convert 10-bit parallel LVCMOS/LVTTL data into a single LVDS serial stream with clock, or reverse the process. Operating frequencies range from 20MHz to 66MHz, supporting data rates up to 660 Mbps. The devices feature IEEE 1149.1 (JTAG) compliance and an at-speed BIST mode for interconnect verification. Power consumption is less than 500 mW for the chipset at 66MHz. Both components are housed in a CTBGA 49-bumps package.

Feature Summary

• Serial Bus LVDS interface supporting 660 Mbps data rate
• IEEE 1149.1 (JTAG) compliant with at-speed BIST test mode
• Single differential-pair data path eliminates multi-channel skew
• Powerdown mode reduces supply current during idle periods

Applications

• Cellular phone base stations
• Add drop muxes and digital cross-connects
• DSLAMs, network switches, and routers
• Backplane interconnect systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the component meets RoHS compliance requirements for your assembly process. Check for any recent product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select the AS1160 for serializing parallel data and the AS1161 for deserializing it. Ensure the system clock frequency falls within the 20MHz to 66MHz range. Verify that the PCB layout supports the required LVDS impedance matching and that the power supply decoupling meets the specifications for AVDD and DVDD pins.

Part Context

The AS1160/AS1161 series serves as a chipset for high-speed serial communication links. It replaces multiple parallel data lines with a single differential pair, simplifying PCB routing and reducing connector size. This solution is particularly useful in applications requiring high bandwidth over short distances with minimal signal skew.
