lm7001jm Sanyo Semiconductor Corporation, lm7001jm Datasheet - Page 6

• Manufacturer Part Number: lm7001jm
• Description: Direct Pll Frequency Synthesizers For Electronic Tuning
• Manufacturer: Sanyo Semiconductor Corporation

Data Input
(1) D0 (LSB) to D13 (MSB): Divisor data
(2) T0 and T1 are LSI test bits and both should be set to 0.
(3) B0 to B2, TB: Band data
FMIN uses D0 to D13 and AMIN uses D4 to D13.
Sample calculation
Note: *:
