VCO + phase comparator for TV
BU2370FV


BU2370FV is a VCO+phase comparator IC used to construct PLL system. Adopting external LPF and divider can
generate the PLL system and low jitter clocks. Output can be switched into half.


zApplications
TV


zFeatures
1) VCO can oscillate output (20MHz to 60MHz)
2) High-speed edge trigger type phase comparator
3) Can control VCO, and phase comparator
independently
4) 3.3V signal power supply
5) Small SSOP-B14 package
