Features
Channels are selectable using pin Channel Selection (CHS) and tuned by a PLL. They do not require any external tank circuit components thus reducing the sensitivity of the PCB design and the need for external adjustments. The PLL obtains its reference from a 4MHz crystal oscillator.

The MC44BC375UA also has the following features.

• Channel selected by CHS pin
• Integrated On-Chip Oscillator - No external tank circuit
• Extremely Low External Components Count
• Adjustable Video Modulation Depth (85% w/o adjustment)
• Peak White Clip
• Programmable Picture/Sound Carrier Ratio (14dB & 16dB) selected by PSS pin
• Integrated On-chip Programmable Sound Subcarrier Oscillator (4.5 & 5.5MHz selected by SFS pin) No external varicaps
• Modulator Standby Mode selected by Psave/LO pin
• Transient Output Inhibit During PLL Lock-up at Power-on
• Logic Output Port selected by Psave/LO pin (Antenna Switch Driver)
• Extremely Robust ESD protection, Minimum 4kV, typical) 6kV.
• Available in 76 dBµV RF output level (MC44BC375U)
• Available in SO16 NB package or QFN20 package (4 x 4 mm, 0.50 mm pitch)
