LA1135M
Overview
- Excellent cross modulation characteristics : Meets the requirements for preventing not only adjacent-channel interference but also interference caused by all channels within broadcast band.
- Narrow-band signal meter output : Usable as auto search stop signal. Has linearity up to 80dBμ.
- Local oscillation buffer output : Facilitates designing of electronic tuner system, frequency display, etc.
- OSC (with ALC) : Improves tracking error because oscillation output is stabilized at a low level (380mVrms) for varactor diode.
- MIX : Double-balanced differential MIX meeting the requirements for preventing spurious interference, IF interference.
- Good characteristics at high input : 130dBμ input, fm = 400Hz 80% mod THD = 0.4% typ
- Low noise : Good S/N at medium input (56dB typ)
- Usable sensitivity : (S/N = 20dB input) : 25dBμ (2SK315 IDSS = 11mA)
- VCC variation compensation : Less variation in gain, distortion : 8 to 12V
- Reduced pop noise : Capable of reducing pop noise at the time of VCC ON, mode select by adjusting AGC time constant. Functions
