Preliminary release of “Advanced” datasheet
Additions include RCO output pin information, pinout drawing, pinout tables,
package dimensions and illustration, duty-cycle diagram, thermal characteristics
table, device reset options table, a section on configuring multiple devices,
bitstream generation and downloading, JTAG information, and Power Consumption
information/illustrations.
Corrections made to pinout drawing and pin names.
Updated RapidConfigure Read Cycle timing diagram so that RCO is relative to
RC_CLK#; RCO was previously relative to RC_EN#. Replaced “+” on signal
names to “P” and “-” to “N”. Corrected RCO[4:0] pin locations.
Corrected pin names ENAB, RCC, and RCE on Pinout drawing and tables to be
OE#, RC_CLK#, and RC_EN# respectively; corrections to Input and Output pin
names 59P, 60P, 61P, and 62P in tables 22 and 23.
Corrected pin names in Table 22 “Pinout By Ball Sequence”:
From
B32 OUT58P
C33 OUT60P
D32 OUT59P
D33 OUT61P
AR9 OUT120P
AT9 OUT120N
Reversed “input” and “output” descriptions in Table 3 “RapidConfigure
Programming Instructions” for instructions 0101, 0111, 1000, 1001, and 1010.
Corrected pin names in Table 22 “Pinout By Ball Sequence”:
From
K5 IN119N
K6 IN119P
AM38 IN597P
AU9 OUT119P
AV9 OUT119N
Changed the V
DC specifications in Table 20; added a note below table explaining the current
values; changed Pass Transistor to high-performance buffering circuit; updated
power and ground pin count in Table 12.
Created separate parts for LVDS and LVPECL (OCX256L and OCX256P
respectively); created new LVDS and LVPECL signal drawings; created new LVDS
and LVPECL power consumption drawings; updated DC electrical specifications
tables; changes/corrections to LVDS and LVPECL DC Electrical Specs tables.
Changes to LVDS and LVPECL power consumption diagrams and Input power
specs.
Changes to LVDS and LVPECL DC Electrical specs tables; added termination
impedance values
Added jitter specifications and PRBS Data Eye diagram.
Swapped Ball Name(s) OUT*P to OUT*N on pinout drawing and tables—Ball
Numbers remain the same.
