WJ Drives Clocks
SAN JOSE, Calif. -- WJ Communications, Inc. (Nasdaq:WJCI) today announces commercial availability of the CA-1249, a densely integrated half-rate clock driver capable of providing the high voltage levels required by optical return-to-zero (RZ) systems for advanced OC-192 fiber optic networks. The CA-1249 is just one model in WJ's portfolio of hybrid-based products optimized for existing and emerging fiber optic networks. The CA-1249 takes a 10.7-12.5 GHz signal and produces a 5.35-6.25 GHz output controllable from 5 to 16V(pk-pk) for driving LiNbO(3) modulators. Analog controlled phase-shift of 360 degrees enables simple control for synchronization and creation of optical RZ pulses. "With orthogonal RF and DC connects, this unique package enables our customers to outsource their line card assembly to surface mount contract manufacturers with little or no RF experience," says James A. Mravca, Senior Vice President, Fiber Optic Products of WJ Communications. "This gives our customers the flexibility and costs savings they need." WJ Communications Inc.
