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.

Applications

TV

Features

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
