NOTES:
1. tSKEW1 is the minimum time between the rising CLKA edge and a rising CLKB edge for
FFB/IRB to transition HIGH in the next cycle. If the time between the rising edge of CLKA and rising
edge of CLKB is less than tSKEW1, then
FFB/IRB may transition HIGH one CLKB cycle later than shown.
2. It is not necessary to program offset register bits on consecutive clock cycles. FIFO write attempts are ignored until
FFA/IRA and FFB/IRB is set HIGH.
3. Programmable offsets are written serially to the SD input in the order
AFA offset (Y1), AEB offset (X1), AFB offset (Y2), and AEA offset (X2).
NOTES:
1. tSKEW1 is the minimum time between the rising CLKA edge and a rising CLKB edge for
FFB/IRB to transition HIGH in the next cycle. If the time between the rising edge of CLKA and rising
edge of CLKB is less than tSKEW1, then
FFB/IRB may transition HIGH one CLKB cycle later than shown.
2.
CSA=LOW, W/RA=HIGH,MBA=LOW. It is not necessary to program offset register on consecutive clock cycles.
