MC13176D overview
MC13176D is a component documented by LANSDALE Semiconductor. The PDF description identifies it as "UHF FM/AM Transmitter." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- Typical Application as 320 MHz AM Transmitter** 50 Ω coaxial balun, 1/10 wavelength at 320 MHz equals 1.5 inches.
- The crystal oscillator circuit may be adjusted for frequency with the variable inductor (ML13175); recommended source is Coilcraft “slot seven” 7mm tuneable inductor, Part #7M3–821.
- The equivalent series capacitance in the differential amplifier is varied by the modulating current from the frequency control circuit (see Pin 6, internal circuit).
- This current is amplified to drive the current source in the oscillator section which controls the frequency of the oscillator.
- Figures 9 and 10 show the ∆fosc versus ICont, Figure 5 shows the ∆fosc versus ICont at – 40°C, + 25°C and +8 5°C for 320 MHz.
- The CCO may be FM modulated as shown in Figure 17, ML13176 320 MHz FM Transmitter.
- 4.0k VCC 4.0k PDout Phase Detector Output The phase detector provides ± 30 µA to keep the CCO locked at the desired carrier frequency.
Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
