Product details

Description

The DP84910 integrates most functions of the hard disk read channel electronics onto a single 5V chip It incorporates a pulse servo detector a programmable integrated channel filter a data synchronizer a frequency synthesizer and a serial port interface The chip receives data from a read preamplifier filters and peak detects the read pulses for both data and embedded servo information and resynchronizes the data with the system clock The DP84910 is available in two versions DP84910VHG-36 and DP8
