Philips Semiconductors
TZA1047
Preprocessor IC for CD and DVD rewritable
s Programmable DC offset cancellation in RF path to allow DC-coupling to Philips
decoder ICs (SAA7810, SAA7811, SAA7846, SAA7849 or PNX7850)
s Programmable Differential Phase Detection (DPD) circuit for DVD radial tracking
s Push-Pull (P-P) signal channel for reading Address In Pre-groove (ADIP) information
on recordable and re-writable media
s Versatile FTC function with programmable ltering
s I2C-bus interface allows the device to be programmed by a decoder IC or
microcontroller
s Works with externally supplied sample timing signals or on-board Eight-to-Fourteen
(EFM) signal decoder for write synchronization
s Programmable normalization for servo signals
s Servo outputs programmable as direct unprocessed currents or as error signals
s Fast running Optimum Power Control (OPC) processing for phase change media
(ALFA loop)
s On-board processing circuit for write power calibration and OPC (BETA loop).
