DESCRIPTION (CONTINUED)
This device includes a Retransmt fromMark feature that utilizes two control
inputs, MARK and ,
RT
(Retransmt). If the MARK input is enabled with respect
to the RCLK, the memory location being read at that point will be marked. Any
subsequent retransmt operation,
RT
goes LOW, will reset the read pointer to
this marked location.
The device can be configured with different input and output bus widths as
shown in Table 1.
A Big-Endian/Little-Endian data word format is provided. This function is
useful when data is written into the FIFO in long word format (x36/x18) and read
out of the FIFO in small word (x18/x9) format. If Big-Endian mode is selected,
then the most significant byte (word) of the long word written into the FIFO will
be read out of the FIFO first, followed by the least significant byte. If Little-Endian
format is selected, then the least significant byte of the long word written into the
FIFO will be read out first, followed by the most significant byte. The mode desired
is configured during master reset by the state of the Big-Endian (
BE
) pin. See
Figure 5 for
Bus-Matching Byte Arrangement
.
The Interspersed/Non-Interspersed Parity (IP) bit function allows the user
to select the parity bit in the word loaded into the parallel port (D
0
-Dn) when
programmng the flag offsets. If Interspersed Parity mode is selected, then the
FIFO will assume that the parity bit is located in bit positions D8, D17, D26 and
D35 during the parallel programmng of the flag offsets. If Non-Interspersed
Parity mode is selected, then D8, D17 and D26 are assumed to be valid bits
and D32, D33, D34 and D35 are ignored. IP mode is selected during Master
Reset by the state of the IP input pin.
If, at any time, the FIFO is not actively performng an operation, the chip will
automatically power down. Once in the power down state, the standby supply
current consumption is mnimzed. Initiating any operation (by activating control
inputs) will immediately take the device out of the power down state.
Both an Asynchronous Output Enable pin (
OE
) and Synchronous Read
Chip Select pin (
RCS
) are provided on the FIFO. The Synchronous Read Chip
Select is synchronized to the RCLK. Both the output enable and read chip select
control the output buffer of the FIFO, causing the buffer to be either HIGH
impedance or LOW impedance.
A JTAG test port is provided, here the FIFO has fully functional Boundary
Scan feature, compliant with IEEE 1449.1 Standard Test Access Port and
Boundary Scan Architecture.
The TeraSync FIFO has the capability of operating its ports (write and/or
read) in either LVTTL or HSTL mode, each ports selection independent of the
other. The write port selection is made via WHSTL and the read port selection
via RHSTL. An additional input SHSTL is also provided, this allows the user
to select HSTL operation for other pins on the device (not associated with the
write or read ports).
The IDT72T3645/72T3655/72T3665/72T3675/72T3685/72T3695/
72T36105/72T36115/72T36125 are fabricated using IDT’s high speed sub-
mcron CMOS technology.
