ISPPAC-CLK5320S-01TN64C

The ispClock5300S is an in-system-programmable zero delay universal fan-out buffer for use in clock distribution applications.
The ispClock5312S, the first member of the ispClock5300S family, provides up to 12 single-ended ultra low skew outputs. Each pair of outputs may be independently configured to support separate I/O standards (LVTTL, LVCMOS -3.3V, 2.5V, 1.8, SSTL, HSTL) and output frequency. In addition, each output provides independent programmable control of termination, slew-rate, and timing skew. All configuration information is stored on-chip in non-volatile E2CMOS® memory.
