PIN DESCRIPTIONS (CONTINUED)
FSYNC
PAFn Bus Sync
LVTTL
FSYNC is an output from the multi-queue device that provides a synchronizing pulse for the
PAFn bus
OUTPUT
duringPolledoperationofthe
PAFnbus.DuringPolledoperationeachsectorofqueuestatusflagsisloaded
on to the
PAFn bus outputs sequentially based on WCLK. The first WCLK rising edge loads sector 1 on
to
PAFn, the second WCLK rising edge loads sector 2. The third WCLK rising edge will again load
sector 1. During the WCLK cycle that sector 1 of a selected device is placed on to the
PAFn bus, the
FSYNC output will be HIGH. For sector 2 of that device, the FSYNC output will be LOW.
FXI

The FXI input is used when multi-queue devices are connected in expansion mode and Polled

bus operation has been selected. FXI of device ‘N’ connects directly to FXO of device ‘N-1’. The FXI
receives a token from the previous device in a chain. In single device mode the FXI input must be tied
LOW if the

must be connected to the FXO output of the same device. In expansion mode the FXI of the first device
should be tied LOW, when direct mode is selected.

(token) is then passed on to the next device in the chain ‘N+1’ and on the next WCLK rising edge the first
sector of device N+1 will be loaded on to the
PAFnbus.ThiscontinuesthroughthechainandFXOofthe
last device is then looped back to FXI of the first device. The FSYNC output of each device in the chain
provides synchronization to the user of this looping event.
ID[2:0](1)
Device ID Pins
LVTTL
For the 16Q multi-queue device the WRADD and RDADD address busses are 8 bits wide. When a queue
INPUT
selection takes place the 3 MSb’s of this 8 bit address bus are used to address the specific device (the
5 LSb’s are used to address the queue within that device). During write/read operations the 3 MSb’s
of the address are compared to the device ID pins. The first device in a chain of multi-queue’s (connected
in expansion mode), may be setup as ‘000’, the second as ‘001’ and so on through to device 8 which
is ‘111’, however the ID does not have to match the device order. In single device mode these pins should
be setup as ‘000’ and the 3 MSb’s of the WRADD and RDADD address busses should be tied LOW. The
ID[2:0] inputs setup a respective devices ID during master reset. These ID pins must not toggle during
any device operation. Note, the device selected as the ‘Master’ does not have to have the ID of ‘000’.
IW(1)
InputWidth
LVTTL
IW selects the bus width for the data input bus. If IW is LOW during a Master Reset then the bus width
INPUT
is x18, if HIGH then it is x9.

data output port, Qout. This flag is therefore, 2-stage delayed to match the data output path delay. That
is, there is a 2 RCLK cycle delay from the time a given queue is selected for reads, to the time the
OVflag
represents the data in that respective queue. When a selected queue on the read port is read to empty,
the
OV flag will go HIGH, indicating that data on the output bus is not valid. The OV flag also has High-
Impedance capability, required when multiple devices are used and the
OV flags are tied together.
OW(1)
OutputWidth
LVTTL
OW selects the bus width for the data output bus. If OW is LOW during a Master Reset then the bus width

is x18, if HIGH then it is x9.
