1540

NTE1540
Integrated Circuit
B/W TV Synchronization, Deflection Circuit
Features:
D Multifunction and small size (16 Lead DIP)
D Minimum number of parts required
D Horizontal and vertical oscillators being stable to variation of ambient temperarture and supply
voltage owing to small warming−up drift.
D Small variation of horizontal oscillation frequency.
D Good linearity and interlace owing to DC bias at vertical output stage being sampling controlled within retrace time.
D Vertical blanking pulse width being freely set up according to peripheral parts.
Functions:
D Synchro Separator
D Horizontal AGC
D Vertical Driver
D Horizontal & Vertical Oscillator
D Vertical Blanking Pulse Making
