Nonuniform pulse code modulation encoder using double polysilicon technology
The logic to drive this array was realized in TTL and consists of about 170 gates, indicating that a total encoder can easily be integrated on a 2.5 X 2.5 mm2 total chip which leaves room enough to inte- grate …
Additionally, these chips have up to a 4 x interpolation done on the chip itself, allowing for 5 Jim position resolution, while still outputting two TTL digital signals. This meant that position could be calculated using standard quadrature encoder hardware or logic .
A 30-MHz trellis codec chip for partial-response channels
As mentioned previously, the encoder , detector, and decoder functions were implemented on the chip . The interleav- ing, deinterleaving, serial-to-parallel conversion, and parallel-to-serial conversion were implemented using off-the-shelf fast TTL logic .
Recent advances in large scale integration (LSI) techniques, however, have resulted in the develop- ment of a monolithic 8 -bit, all- parallel encoder which operates at a reasonable power level though requiring additional off - chip circuitry to make it a complete A/D … In TTL , the logic time skew depends upon the direction of the transition.
