TZA1015T Description
TZA1015 The TZA1015 is a data amplifier and laser supply circuit for 3-beam pick-up detectors found in a wide range of CD and read-only optical systems. The device contains 6 transimpedance amplifiers to amplify and filter the focus and radial photo diode voltage input signals. The preamplifier forms a versatile, programmable interface from voltage output CD mechanisms to the Philips’ digital signal processor family.
TZA1015T Key Features
- Six input buffer amplifiers with low-pass filtering and virtually no offset
- Universal photodiode IC interface using internal conversion resistors
- RF data amplifier with wide bandwidth designed for data rates up to a maximum of 30×
- Programmable RF gain for CD-A/V, CD-R, CD-R/W and CD-ROM
TZA1015T Applications
- Programmable RF bandwidth for optimal playability
- Radial error signal for fast track counting
- Programmable RF/Fast Track Count (FTC) gain for optimal dynamic range
- Fully automatic laser control including stabilization and on/off switch plus a separate supply for power efficiency
