Overview
INTEGRATED CIRCUITS DATA SHEET P32P4911A PRML Read Channel with PR4, 8/9 ENDEC, FWR Servo Product Specification 1996 Jul 25 Philips Semiconductors Product specification PRML Read Channel with PR4, 8/9 ENDEC, FWR Servo GENERAL DESCRIPTION P32P4911A The Philips Semiconductors P32P4911A is a high performance BiCMOS read channel IC that provides all of the functions needed to implement an entire Partial Response Class 4 (PR4) read channel for zoned recording hard disk drive systems with data rates from 42 to 125 Mbit/s or 33 to 100 Mbit/s.
Functional blocks include AGC, programmable filter, adaptive transversal filter, Viterbi qualifier, 8,9 GCR ENDEC, data synchronizer, time base generator, and FWR servo.
Programmable functions such as data rate, filter cutoff, filter boost, etc.
, are controlled by writing to the serial port registers so no external component changes are required to change zones.
The part requires a single +5V power supply.
