Features
Freescale Semiconductor, Inc.
1 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 sound subcarrier is also generated on-chip without external components. The 4.5MHz or 5.5MHz
Sound frequency is selectable using pin Sound Frequency Selection (SFS). The Picture to Sound subcarrier
ratio is also selectable by pin Picture to Sound selection (PSS) to either 14dB or 16dB. A Power Save
function is selectable via pin Psave/LO which turns off all internal VCOs and mixers and simultaneously
switches ON the Logic Output Port (LOP). No external Varicap Diodes/ Inductor nor other tuned
components are needed.
The MC44BC375/U/J/T 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 80 dBuV RF output level (MC44BC375UA).
