TA1326FNG

www.DataSheet4U.com TA1326FNG TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA1326FNG UHF Band RF Modulator IC for VTRs The TA1326FNG is a UHF band RF modulator IC that features PLL-based RF carrier and audio intercarrier oscillation. The TA1326FNG is compatible with PAL and NTSC television systems and is lower in cost than TA1243 or TA1297 Series devices. Features PLL-based RF oscillator for full UHF band operation (channels 21~69) SSOP16-P-225-0.65B Weight: 0.07 g (typ.) PLL-based audio intercarrier oscillator which can support both PAL and NTSC television systems without any adjustment Formats supported: M/G/H/I/D Mode control using I2C bus RF carrier frequency (10 bits, in 1-MHz steps) Audio intercarrier frequencies (4.5 MHz, 5.5 MHz, 6.0 MHz and 6.5 MHz) P/S ratio setting (−10dB to −17dB in 1dB steps) Test pattern generator White Clip Through Mode Muted RF output on power-on and as required Terminal of Package is improved to Lead-Free. m o .c U 4 t e e h S a at .D w w w Pins numbered 2 and 7 of this product are sensitive to electrostatic discharge.
