The

µPB587G is a divide by 2/4/8 prescaler for portable VHF/UHF TV and radio applications. This IC operates

up to 1 GHz with 2.2 to 3.5 V bias supply by utilizing highly efficient ECL process technology. This IC is packaged

in 8 pin SOP.

Thus, this IC can contribute to produce a physically small and low voltage PLL synthesizer in conjunction

with DTS microcomputer 17K series.
