DESCRIPTION
P
PD2845GR 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. So, this product contributes to produce a long-life-
battery and physically-small pager system.
