BA7358S General Description
The BA7358S is multi-format (M, B / G, D / K, and I) VIF / SIF signal processor for television and VCR applications. It
features separate-carrier PLL with full synchronous detection and employs a pulse-count detector audio system that
does notrequire adjustment. It also includes a sound trap band-pass filters that use our independently-developed filter technology. This IC reduces external component requirements, and allows space savings.
BA7358S Maximum Ratings
| Parameter | Symbol | Limits | Unit |
| Applied voltage | VCCMax. | 10.5*1 | V |
| Power dissipation | PdMax. | 1250*2 | mW |
| Operating temperature | Topr | 15 ~ + 70 | |
| Storage temperature | Tstg | 40 ~ + 150 | |
| Pin 2 applied voltage | VP2Max. | 10.5 | V |
*2 When IC is stand alone, reduced by 10mW for each increase in Ta 1 over 25.
BA7358S Features
· 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.
· The IF AGC time constant is dual-layered to allow faster speeds.
· The variable-gain amplifier has excellent linearity to ensure low distortion, and AGC variance and temperature drift have been minimized.
· Built-in SOUND filter (SOUND trap and SOUND BPF).The MODE switch can be used to switch between M, B / G, I, and D / K (4.5MHz, 5.5MHz, 6.0MHz, and 6.5MHz respectively). In particular, the SOUND BPF gives a larger attenuation ratio than conventional discrete circuits by using two-layer SIF + 500kHz BPFs.
· The audio detector uses a 500kHz beatdown pulsecounter detector that does not require adjustment. This eliminates the need for a detector coil and gives better linearity and S / N.
· 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.
