BA7357S Features
1) Separate-carrier PLL with full synchronous detection. Excellent DG / DP, CS beat (920kHz) and cross color. In addition, by pulling down the SIF input (pin 9) it can be used as an intercarrier.
2) The IF AGC time constant is dual-layered to allow faster speeds.
3) The variable-gain amplifier has excellent linearity to ensure low distortion, and AGC variance and temperature drift have been minimized.
4) Significant improvement in image quality through use of a filter that reduces CS beat.
5) Built-in SOUND filter (4.5MHz SOUND Trap and 4.5MHz SOUND BPF). The MODE switch can be used to switch the SOUND filter frequency band to match the transmission format (M: 4.5, B / G: 5.5, I: 6.0, D / K: 6.5MHz).
6) The audio detector uses a pulse-counter detector that does not require adjustment, eliminating the need for a detector coil. Broad S-curve for multiplex broadcast compatibility.
7) Use of pulse-counter detection and the built-in SOUND filter means fewer pins, external components and adjustment locations are required. The IC is available in a 22-pin SDIP package and will enable cost and space savings.
