LED Tuning Indicator
Use
Indicates tuning condition of FM receiver by means of 5
mode – 3 LEDs.
Features
• 3 LEDs display 5 mode tuning condition.
Since the LEDs are driven under constant current supply,
the LED current varys as shown below when two LEDs
are lighted on simultaneously. This causes their bright-
ness to vary, and enables the dynamic indication.
• Desired tuning width can be set as the threshold width of
window comparator is variable externally.
• No switching radiation can be made as LED current
changes over linearly.
• Blanking at station interval and AM reception is easy to
set by blanking pin.
• Direct interface can be made to IF IC using quadrature
detector (ex. LA1231, LA1140, etc.)
• Single-ended 9 pin package with small mounting area.
