Clock ICs offer programmable output

The ispClock5400D family of differential clock distribution ICs, featuring the CleanClock low-phase-noise PLL, contains the six-output ispClock5406D and 10-output ispClock5410D. The FlexiClock output section of the family supports multiple logic standards (LVDS, MLVDS, HCSL, LVPECL, HSTL, and SSTL) and dual-skew programmable-control features.

The devices also include an on-chip programmable analog filter and a programmable VCO with input clock frequencies up to 400 MHz. The configuration of each device is held in on-chip nonvolatile memory that is reprogrammable through a JTAG interface. Certain aspects of the device can be modified on the fly via an I2 C interface. (Ea/1,000: ispClock5406D, $3.95; ispClock5410D, $5.50 — available now.)
