BU2374FV Datasheet | ROHM

Description General-purpose VCO Series ICs (BU2373FV and BU2374FV) have a built-in VCO and phase parator and facilitate the configuration of a PLL system through the external connection of a LPF and frequency divider. Furthermore, in order to facilitate the loop constant settings of the PLL system, the application manual has been enhanced to ensure studies on the application. - Features 1) The VCO enables midpoint settings within the range of oscillation through the external resistance. 2) The rising edge trigger type of phase parator is built in. 3) Power-down mode setting can be made independently with the VCO and the phase parator. 4) The VCO output frequency division can be selected on the SELECT pin. 5) pact SSOP-B14 Package is adopted. - Applications CRT, LCD monitor, and CD-RW - Line up matrix VDD=3.0V Supply voltage VDD=3.3V VDD=5.0V Frequency range VDD=3.0V VDD=3.3V VDD=5.0V VCO-Frequency dividing mode Operating temperature range Package BU2373FV ○ ○ ○ 37～60MHz 37～65MHz 43～100MHz 1/2 -20～75℃ SSOP-B14 － ○ － － 37～60MHz － 1/4 -20～75℃ SSOP-B14 - Absolute maximum ratings (Ta=25℃) Symbol Ratings Supply voltage -0.5～7.0 Input voltage VIN -0.5～VDD+0.5 Storage temperature range Tstg -30～125 Power dissipation Pd 400 - 1 Operating is not guaranteed. - 2 In the case of exceeding Ta = 25℃, 4.0m W should be reduced per 1℃. - 3 The radiation-resistance design is not carried out. - 4 Power dissipation is measured when the IC is mounted to the printed circuit board.
