ANALOG DEVICES DIGITAL-TO-SYNCHRO CONVERTERS The DSC1605 and 1606 series are digital to synchro converters capable of driving electromechanical loads of up to 1.3VA. Inputs are parallel natural binary angle plus a 60Hz or 400Hz reference. Outputs are 3 wire synchro or 4 wire resolver format. Reference input and synchro/resolver output are transformer isolated with up to a 500V de common mode voltage capabili- ty. 60Hz versions have the transformers in a separate module. S/D and D/S Converters The DSC1607 series feature 16 bit binary input. Power ampli- fication and transformer isolation are not provided. The sine/ cosine outputs are individually amplitude corrected vs. angle to better than 1%, a feature not included in the DSC1605/1606 series. This amplitude correction is important in type 1 servo control loop applications.

TWO SPEED S/D CONVERTERS SPECIFICATION SUMMARY TSL1612500 The TSL and TSDC series of converters provide a digital solu- tion to the problem of combining the multiple speed outputs from a pair of two speed synchros to a single speed output word. The TSL1612 provides the two speed logic for the non-binary speed ratios of either 36:1 or 18:1 (36:2) or 9:1 by simple pro- gramming cf the input/outputs. The TSL1612 accepts a binary angle input of up to 14 bits from a fine channel converter plus a second input of up to 7 bits from a coarse channel converter and provides a single speed output word of up to 19 bits par- allel binary angle. The TSDC series provides a dual function: conversion of coarse channel synchro data to 10 bit binary via a tracking S to D con- verter plus performing two speed processing for binary speed ratios. The converter portion is identical to the SDC1603 speci- fied elsewhere. Binary ratios of 8:1, 16:1, 32:1 and 64:1 together with a 10 bit converter are provided by the TSDC1608, TSDC- 1609, TSDC1610 and TSDC1611 series respectively. A fine channel converter of up to 16 bits binary completes this two speed set.
