Objective data sheet
2.2 Read formats
Slave I
speed to an input I
Integrated digital HF/mirror detector with measurement of minimum and maximum
peak values, amplitude and offset
Integrated LCD controller/driver (pins multiplexed with General Purpose Input/Outputs
(GPIOs)
Integrated CD-TEXT decoder
1 , 2 , 4
QFP100 package with 0.65 mm pin pitch
Separate left and right channel digital silence detect available on KILL pins
Digital silence detection available on loopback data from external source as well as
internal data
‘Filterless’ pseudo-bitstream audio DAC; THD = 80 dB and S/N = 90 dB; with minimal
external components
Separate line and headphone outputs for audio DAC
Selectable quiescent current for headphone buffers - allows users to choose between
low-power consumption or lower distortion performance
Loop back mode allowing the use of integrated DAC with external I
sources
Compatible with voltage mode mechanisms
On-chip buffering and filtering of the diode signals from the mechanism in order to
optimize the signals for the decoder and servo parts
LF (servo) signals converted to digital representations by sigma delta ADCs shared
between pairs of channels to minimize DC offset between channels
HF part summed from signals D1 to D4 and converted to digital signals by HF 6-bit
ADC
Digitally controlled selectable DC offset cancellation of quiescent mechanism voltages
and dark currents; additional fine DC offset cancellation in digital domain
Eye pattern monitor system to observe selectable points within the analog preamplifier
Current and average jitter values available via registers
On-chip laser power control; up to maximum currents of 120 mA
Laser on-off control; including ‘soft’ start control - zero to nominal output power in 1 ms
Monitor control and feedback circuit to maintain nominal output power throughout the
life of laser
Configured for Nsub monitor diode
JTAG interface for device access and ARM code development (compatible with ARM
multi-ICE)
All digital input pins 5 V tolerant.
CD-R
