TA2153FN
RF Amplifier for Digital Servo CD System
TA2153FN
TA2153FN is a 3-beam type PUH compatible RF amplifier for
digital servo to be used in the CD system.
In combination with a CMOS single chip processor
TC9462F/TC9495F, a CD system can be composed very simply.
Features
· Built-in amplifier for reference (VRO, 2VRO) supply.
· Built-in auto laser power control circuit.
· Built-in RF amplifier.
· Built-in AGC amplifier.
· Built-in focus error amp and tracking error amp.
· Built-in sub-beam adder signal amplifier.
· Built-in gain change circuit for CD-RW.
· Capable of tracking balance control with TC9462F/TC9495F.
· Capable of RF gain adjustment circuit with TC9462F/TC9495F.
· Built-in signal amplifier for track counter.
· Capable of 4 times speed operation.
· 30 pin mini flat package.
