ispPAC-CLK5312S-01T48C General Description

The ispClock5300S is an in-system-programmable zero delay universal fan-out buffer for use in clock distributionapplications. The ispClock5312S, the first member of the ispClock5300S family, provides up to 12 single-endedultra 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 onchip in non-volatile E2CMOS® memory.

The ispClock5300S devices provide extremely low propagation delay (zero-delay) from input to output using theon-chip low jitter high-performance PLL. A set of three programmable 5-bit counters can be used to generate threefrequencies derived from the PLL clock. These counters are programmable in powers of 2 only (1, 2, 4, 8, 16, 32).The clock output from any of the V-dividers can then be routed to any clock output pin through the output routingmatrix. The output routing matrix, in addition, also enables routing of reference clock inputs directly to any output.The ispClock5300S device can be configured to operate in four modes: zero delay buffer mode, dual non-zerodelay buffer mode, non-zero delay buffer mode with output dividers, and combined zero-delay and non-zero delaybuffer mode.
