NJM2540/2543
Mixer and Oscillator for TV Tuner
DESCRIPTION The NJM2540/43 are mixer/oscillator especially designed for TV tuners and consists of mixers, oscillators, IF amplifier and OSC buffer for VHF,UHF and CATV band, built into one chip. The NJM2540/43 packaging in SSOP16 are suitable for small-sized tuners. The NJM2543 is the reverse pin assignment type of the NJM2540. FEATURES · Operating Voltage 5V · Mixers, Oscillators, IF AMP and OSC buffer on chip · Bipolar Technology · Package Outline: SSOP16 PACKAGE OUTLINE
