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.
