Nisshinbo Micro Devices Inc. Linear - Video Processing NJM2536AM#

The NJM2536AM# is an RF modulator IC designed specifically for VHF band applications. It integrates several functions including a video clamp circuit, white clip circuit, video AM modulator, and audio FM modulator into a single chip, which simplifies design and reduces component count. This device operates at a voltage range of 4.5V to 5.5V, with a typical operating voltage of 5V. It features an adjustable picture-to-sound ratio, an on-chip VHF oscillator, and a carrier-off switch function. The NJM2536AM# is built using bipolar technology and comes in a DMP/SSOP14 package. Key electrical characteristics include a typical operating current of 16.0 mA at 5V, a video output level ranging from 83 dBu to 89 dBu, and a video modulation depth of up to 82%. The device also supports audio modulation with a total harmonic distortion of 0.3% and a sound signal-to-noise ratio of 60 dB. Engineers looking for a compact and integrated solution for RF modulation in VHF applications may find the NJM2536AM# suitable for their projects.
