CDR/demultiplexer and transimpedance chipset
The cdr300 family, which includes the cdr3300 combined clock and data recovery/demultiplexer gate array and transimpendance amplifiers, targets receiver designs for sdh and sonet transmission systems. The cdr receives scrambled non-return to zero signals and recovers clock and data information at speeds to 3.3 Gbits/sec. The bipolar device also provides a demultiplexer that can be configured to customer requirements. The device also integrates a phase locked loop circuit with a linear, voltage-controlled oscillator, plus a circuit for level-independent, sdh-compatible detection of loss of signal. The transimpedance amps are designed for equipment in lan/wan applications such as atm switches, optical transceivers, signal regenerators, hubs, and routers. The cdr/demultiplexer is available at $110 in orders of 1000. The transimpedance amplifiers ship for $10.50 (data rate 622 Mbits/sec) to $42 (data rate 0.5 Gbits/sec) for 1000.
