SCAN921260
X6 1:10 Deserializer with IEEE 1149.1 (JTAG) and
at-speed BIST
General Description
The SCAN921260 integrates six deserializer devices into a
single chip. The SCAN921260 can simultaneously deserial-
ize up to six data streams that have been serialized by the
National Semiconductor SCAN921023 Bus LVDS serializer.
The device also includes a seventh serial input channel that
serves as a redundant input.
Each deserializer block in the SCAN921260 operates inde-
pendently with its own clock recovery circuitry and lock-
detect signaling.
The SCAN921260 uses a single +3.3V power supply with an
estimated power dissipation of 1.2W at 3.3V with a PRBS-15
pattern. Refer to the Connection Diagrams for packaging
information.
Features
n IEEE 1149.1 (JTAG) Compliant and at-speed BIST test
modes
n Deserializes one to six BusLVDS input serial data
streams with embedded clocks
n Seven selectable serial inputs to support n+1
redundancy of deserialized streams
n Seventh channel has single pin monitor output that
reflects input from seventh channel input
n Parallel clock rate up to 66MHz
n On chip filtering for PLL
n High impedance inputs upon power off (Vcc = 0V)
n Single power supply at +3.3V
n 196-pin LBGA package (Low-profile Ball Grid Array)
package
n Industrial temperature range operation: −40 to +85
