RF amplifier for Car CD
BH3514BFV
Description
The BH3514BFV is a RF amplifier for Car CD players
that has a built-in equalizer circuit (EQ). The equalizer
circuit is applied to x1, x2 and x4 speeds. The equalizer
circuit has improved characteristics, which will enhance
the overall performance during mobile jitter conditions.
Boost quantity and phase characteristics can also be
controlled. Gain up SW for CD-R/RW is incorporated
and is available for multi-reads. LD voltage can be
switched in 3-steps. This RF amplifier is available for
each pick.
