DS92LV8028
SNLS152I – NOVEMBER 2001 – REVISED APRIL 2013

The @SPEED feature uses 5 signal pins. The BIST_SEL[0:3] and BIST_ACT pins together determine the
functions of the BIST mode. The BIST_ACT signal activates the test feature. The BIST_SEL[0:2] select 1 of 8
channels as the output for the BIST pattern. All channels perform BIST when BIST_ACT = H and
BIST_SEL[0:3]=08H.
The JTAG pins are reserved on this version of the serializer. They will be JTAG compliant functionality on the
next version. The @SPEED test will also be available through a JTAG command when available.
Truth Table (BIST mode)
No BIST function performed when BIST_SEL (0:3) are set from 9H to FH even when BIST_ACT is set at HIGH. See ⁽¹⁾
