WD10C23

The WD10C23 read/write channel isan LSI device implemented in 1.25 micron high-speed CMOS.WD10C23 is specially designed to be compatible with the western digital WD53C22/42C22/WD50C12 series of hard disk controllers, and with disk drives conforming to the popular ST506/412 interface standard and recent speed-enchanced versions.In addition it will support optical applications when used with the WD60C31A ENDEC.

WD10C23 has many unique features: The first one is 5-15 M bit/sec data rates with no component changes.The second one is fixed/variable frequency control for zone bit recording.The third one is pin selectible hard/soft sector support and 2,7 RLL coding.The forth one is crystal controlled processing of the write data.The fifth one is frequency independent data detection window optimization,etc.

There are some maximum ratings about WD10C23.Voltage on any pin with respect to ground(except XTALIN) is -0.5 V to Vcc+0.5 V.Storage temperature is -55 to 125.Operating temperature is 0 to 70.Voltage on XTALIN with respect to ground is -0.1 V to Vcc+0.5 V.Supply voltage with respect to ground is 5.5 V.
