UPD2845GR - 1 V 1.3 mA 94MHz PLL SYNTHESIZER LSI

General Description

PPD2845GR is a PLL synthesizer LSI for pager system.

This LSI is manufactured using low voltage CMOS process and therefore realized the low power consumption PLL operated on 1 V, 1.3 mA.

This LSI is packaged in 16 pin plastic SSOP suitable for high-density surface mounting.
