GENERAL DESCRIPTION
The TZA1046 is a single optical pick-up IC for read/write systems and is suitable for CD and DVD applications.
The device contains eight RF amplifiers for the central and satellite diodes and one differential RF amplifier (RFP and RFN) which handles the sum of the four A, B, C and D central diode signals.
FEATURES
• High frequency RF amplifiers
• Power-down mode for standby condition
• Suitable for all CD (785 nm) and DVD (655 nm) read/write applications
• Four high-bandwidth central outputs (A, B, C and D); four satellite outputs (EG, FH, ETST and HTST) and one high-bandwidth differential RF output (RFP and RFN)
• Internal current clamp and current fold back (power reduction)
• Versatile programmable gain switches (CD/DVD, H/L and R/W)
• Single 5 V supply
• Current outputs for optimum signal transport over flex cable
• Small outline package HTSSON16T with good positional tolerance.
