5 / 8 page No. 5473-5/8 LA7437, 7437A LA7437A Control Pin Table Note: Do not allow pin 3 to fall under 1.5 V. (The chip will enter test mode.) Function Control in each of the LA7437A Operating Modes Note: 1. K1 is the YNR coefficient, K2 is the LNC coefficient 2. Use the 1/2 fH carrier shift entries in parentheses when pin 23 is high. 3. The detail enhancer is off when pin 18 is at the middle level.
