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.
