AS1160/AS1161
20MHz - 66MHz, 10-Bit Bus, IEEE 1149.1 (JTAG)
Compliant LVDS Serializer/Deserializer

Datasheet
1 General Description
The AS1160 (serializer) is designed to convert 10-bit
wide parallel LVCMOS/LVTTL data bus signals into a
single high-speed LVDS serial data stream with clock.
The AS1161 (deserializer) transforms the high-speed
LVDS serial data stream back into a 10-bit wide parallel
data bus with recovered parallel clock.
Both devices are compliant with IEEE 1149.1 Standard
Test Access Port and Boundary Scan Architecture
(including the defined boundary-scan test logic and test
access port consisting of Test Data Input, Test Data O ut,
and Test Mode Select, Test Clock, and Test Reset).
The devices also feature an at-speed BIST mode which
allows the interconnects between the serializ er and
deserializer to be verified at-speed.
The single differential-pair data-path makes PCB design
easier, and reduced cable/PCB-trace count and connec-
tor size significantly reduce cost. Since one output trans-
mits clock and data bits serially, clock-to-data and data-
to-data skew are eliminated.
Powerdown mode reduces supply current when both
devices are idle.
Both devices are available in a CTBGA 49-bumps pin
package.
