With new Guzik RWA4000 TDMR, UP14 allows to process signals from three Read Channels. It also supports two high speed data channels for Write data and Laser data. UP14 has two channels for dynamic TFC control and allows to program TFC power per sector and close loop TFC power control in each channel. UP14 can generate two programmable modulation signals for write data and laser data with bandwidth up to 20 MHz. UP14 consist of two boards. The first UP14 RW Board processes high-frequency signals: read-back signals, write data and laser data. The second UP14 Control Board provides power, control and low-frequency signal generation: TFC, write data modulation and laser modulation.
