• Manufacturer Part Number: cyv15g0404dxb
• Description: Independent Clock Quad Hotlink Ii Transceiver With Reclocker
• Manufacturer: Cypress Semiconductor Corporation.

3-Level Select Inputs
Each 3-Level select inputs reports as two bits in the scan register.
These bits report the LOW, MID, and HIGH state of the
associated input as 00, 10, and 11 respectively.
JTAG ID
The JTAG device ID for the CYV15G0404DXB is ‘0C811069’x
.

Normal character received. The valid Data
character on the output bus meets all the
formatting requirements of Data characters
listed in
Special code detected. The valid special
character on the output bus meets all the
formatting requirements of Special Code
characters listed in
presently selected framing character or a
decoder violation indication.
Receive Elasticity buffer underrun/overrun
error. The receive buffer was not able to
add/drop a K28.5 or framing character
Framing character detected. This indicates
that a character matching the patterns identified
as a framing character (as selected by
FRAMCHARx) was detected. The decoded
value of this character is present in the
associated output bus.
Codeword violation. The character on the
output bus is a C0.7. This indicates that the
received character cannot be decoded into any
valid character.
Loss of sync. This indicates a PLL Out of Lock
condition
Running disparity error. The character on the
output bus is a C4.7, C1.7, or C2.7.

Description
BIST Data Compare. Character compared correctly.
BIST Command Compare. Character compared
correctly.
BIST Last Good. Last Character of BIST sequence
detected and valid.
BIST Last Bad. Last Character of BIST sequence
detected invalid.
BIST Start. Receive BIST is enabled on this channel,
but character compares have not yet commenced. This
also indicates a PLL Out of Lock condition, and
Elasticity Buffer overflow/underflow conditions.
BIST Error. While comparing characters, a mismatch
was found in one or more of the decoded character bits.
BIST Wait. The receiver is comparing characters. but
has not yet found the start of BIST character to enable
the LFSR.
(Receive BIST = Enabled)
