MC10E197
5V ECL Data Separator
The MC10E197 is an integrated data separator designed for use in
high speed hard disk drive applications. With data rate capabilities of
up to 50 Mb/s the device is ideally suited for today’s and future
state-of-the-art hard disk designs.
The E197 is typically driven by a pulse detector which reads the
magnetic information from the storage disk and changes it into ECL
pulses. The device is capable of operating on both 2:7 and 1:7 RLL
coding schemes. Note that the E197 does not do any decoding but
rather prepares the disk data for decoding by another device.
For applications with higher data rate needs, such as tape drive
systems, the device accepts an external VCO. The frequency
capability of the integrated VCO is the factor which limits the device
to 50 Mb/s.
A special anti-equivocation circuit has been employed to ensure
timely lock-up when the arriving data and VCO edges are coincident.
Unlike the majority of the devices in the ECLinPS family, the E197
is available in only 10H compatible ECL. The device is available in
the standard 28-lead PLCC.
Since the E197 contains both analog and digital circuitry, separate
supply and ground pins have been provided to minimize noise
coupling inside the device. The device can operate on either standard
negative ECL supplies or, as is more common, on positive voltage
supplies.
