1 / 12 page  80807 MS PC 20061214-S00006 No.A0654-1/12 Specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer 's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer 'sproductsor equipment. Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.). The products mentioned herein shall not be intended for use for any "special application" (medical equipment whose purpose is to sustain life, aerospace instrument, nuclear control device, burning appliances, transportation machine, traffic signal system, safety equipment etc.) that shall require extremely high level of reliability and can directly threaten human lives in case of failure or malfunction of the product or may cause harm to human bodies, nor shall they grant any guarantee thereof. If you should intend to use our products for applications outside the standard applications of our customer who is considering such use and/or outside the scope of our intended standard applications, please consult with us prior to the intended use. If there is no consultation or inquiry before the intended use, our customer shall be solely responsible for the use. LA75520KVA Overview The LA75520KVA is a fully adjustment-free VIF + SIF signal processing IC for TV sets and VTRs that supports the PAL video standard. It supports 38.0MHz, 38.9MHz, and 39.5MHz as the IF frequencies, as well as PAL sound multi-system (M/N, B/G, I and D/K), and contains an on-chip sound carrier trap. The IC employs a 4MHz frequency (which can be switched to 4.43MHz) as the reference frequency of the adjustment free circuit, and controls the VCO, AFT, and sound filter using an external input signal. Features • Internal VCO adjustment free circuit eliminating the need for an external VCO coil. • Internal sound carrier trap enables easy configuration of PAL sound multi-system at low cost. • Considerably reduces the number of required peripheral parts. • Use of digital AFT eliminates a problem of AFT tolerance. • Package: SSOP24 (225mil) Functions • VIF amplifier • EQAMP • Adjustment-free VCO and PLL detector circuit • Internal sound carrier trap • Digital AFT circuit • First SIF detector circuit • RF AGC • PLL-FM detector circuit • Buzz canceller Ordering number : ENA0654 Monolithic Linear IC IF Signal Processing (VIF+SIF) IC that Supports the PAL Video Standard for TV Sets and VCRs |
