TZA1024T - NXP

TZA1024T Data amplifier and laser supply circuit for CD audio and video optical systems ADALAS

TZA1024 The RF bandwidth allows this device to be used in CD-A/V and CD-R/W applications with a data rate up to a maximum of n = 4 times speed. The RF gain can be adapted for CD-A/V discs or CD-R/W discs by means of the gain select signal. The equalizer can be adjusted for n = 1 or n = 2 times speed with the equalizer/speed select signal. For n = 4 times s.
