AN5101NSC
VIF/SIF IC for TV and VCR
■ Overview
Unit : mm
The AN5101NSC is a VIF/SIF signal process-
ing IC for TV and VCR. Reduction of sound noise
and improvement of picture quality have been real-
ized by adoption of the gated PLL detection sys-
tem.

Standards in advance to make sure that the latest specifictions saisfy your requirements.
(5) When designing your equipment, comply with the rnge f absolute maximuing nd the guaranteed operating conditions
(operating power supply voltage and operating nvirnt etc.). Especiallyplee be creful not to exceed the range of absolute
maximum rating on the transient state, such as powpower-off and mode-witching. Otherwise, we will not be liable for any
