SYSTEM DESCRIPTION
PulseDetector Section
Fast attack/decaymodes for rapid AGC recovery.
Dual rate charge pump for fast transient recovery.
Low Drift AGC hold circuitry supports programma-
ble gain, non-AGC operation. Temperature com-
pensated,exponentialcontrol AGC. Shorted input
switch for transient recovery, during Power down
& Write to read & Idle mode transitions. Wide
Bandwidth, high precision full-wave rectifier. Dual
mode pulse qualification circuitry allows either in-
dependentpositive and negativethresholdqualifi-
cation to suppresserror propagation or hysteresis
comparison wich implements alternating polari-
ties. Differential qualifier comparator. TTL READ
DATA I/O signal
output available during servo
and idle modes. Timing for shorted inputs and
fast decay functions set internally. 0.5 ns max.
pulse pairing with sine wave input.
Embedded ServoDemodulator Section
Dual servo burst (A/B) capture with Position Error
Signal Output. ServoAGC mode whichholds sum
of A and B bursts constant. Provision for on-chip
switching of the hysteresis threshold time con-
stant.
ProgrammableFilter Section
Programmable filter cutoff frequency (fc = 6 to 18
MHz). Programmable pulse slimming equalization
(0 to 9 dB Boost at the filter cutoff frequency).
Matched path timing normal and differential low-
pass outputs. Differential filter input and outputs
for noise rejection
±
10% cutoff frequency accu-
racy.
±
2% maximum group delay variation in the
passband maintained over the cutoff frequency
tuning range ( fc=6 to 18 MHz ). Total harmonic
distortion less than 1.5 %. No external filter com-
ponents required. Shorted input switch for tran-
sient recovery, during Power down & Write to
Read & Idle mode transitions.
Frequency Synthesizer and Data Separator
Section
1% frequency resolution. Data synchronizer and
1.7 RLL ENDEC. Fast acquisition phase lock loop
with zero phase restart both to data and synthe-
sizer. Fully integrated data separator. No external
delaylines or activedevices required. No external
active PLL components required. Active window
centering symmetry control via serial port. Win-
dow shift control
±
30%. Includes delayed read
data and VCO clock monitor tests points. Pro-
grammable write precompensation.Hard and soft
sectoroperation.
