Overview

CXA3135AN All Band TV Tuner IC with On-chip PLL For the availability of this product, please contact the sales office.
Description The CXA3135AN is a monolithic TV tuner IC which integrates local oscillator and mixer circuits for VHF band, local oscillator and mixer circuits for UHF band, an IF amplifier and a tuning PLL onto a single chip, enabling further miniaturization of the tuner.
The PLL on this IC supports the I2C bus format.
Features • Low noise figure • Low power consumption (5 V, 54 mA typ.
) • On-chip tuning PLL (I2C bus format) • Selection of frequency steps 31.
25 kHz, 50 kHz and 62.
5 kHz • On-chip 4-output band switch Applications • TV tuners • VCR tuners • CATV tuners Structure Bipolar silicon monolithic IC 30 pin SSOP (Plastic) Absolute Maximum Ratings (Ta = 25 °C) • Supply voltage VCC1,VCC2 –0.
