LM1880 Overview
Key Specifications
Length: 22.352 mm
Description
The LM1880 uses compatible Linear I2L technology to produce the first T V horizontal and vertical processing system which completely eliminates the hold controls The heart of the system is a precision 32 times horizontal frequency VCO which is designed to use a low-cost ceramic resonator as a tuning element The VCO signal is divided down in the horizontal section to produce a pre-driver output which is locked to negative sync by means of an on-chip phase detector The vertical output ramp is injection-locked by vertical sync subject to a sync window derived from the vertical countdown section A gate pulse centered on the chroma burst is also provided.
