Q1601

The Q1601 is designed as viterbi decoder which provides the ideal solution for high-volume, cost-sensitive systems which require the coding gain of the viterbi algorithm. Its typical applications include digital open satellite networks, digital audio broadcost, microwave point-to-point, spread spectrum systems, direct broadcast systems, digital video reception and high speed data communications.

Q1601 has many features. The first one is low cost viterbi decoder. The next one is 10Mbps data rate. The next one is on-chip channel bit error rate monitor. The next one is no high-speed computational clock required. The next one is rate 1/2 coding gain of 5.2dB at 10^-5 BER. The next one is hard or soft decision (8-level) decoder inputs. The next one is parallel or serial inputs. The next one is microprocessor interface eases control. The next one is CCITT V.35 descrambler. The next one is automatic synchronization to QPSK / BPSK / OQPSK modems. The next one is single chip decoder for highest reliability. The next one is standard PLCC package simplifies design and assembly.

Some absolute maximum ratings of Q1601 have been concluded into several points as follow. The first one is about its storage temperature range which would be from -65°C to +150°C. The next one is about its operating temperature range which would be from 0°C to +70°C. The next one is about its junction temperature which would be max +150°C. The next one is about its voltage on any input pin which would be from -0.3V to Vdd+0.3V. The next one is about its voltage on Vdd and on any output pin which would be from -0.3V to +7.0V. The next one is about its DC input current which would be min -10uA and max +10uA. It should be noted that stressesabove those listed under "absolute maximum ratings" may cause permanent damage to the device. And so on. For more information please contact us.
