1 / 29 page Ordering number : ENN6976A 82102TN (OT) / 83101RM (OT) No. 6976-1/29 Overview The LC72151V is a PLL frequency synthesizer for car audio systems. It can implement high-performance multifunction tuners such as RDS tuners and features a fast locking circuit. Functions • High-speed programmable divider — FMIN: 10 to 160 MHz: Pulse swallower type — AMIN: 2 to 40 MHz: Pulse swallower type 0.5 to 10 MHz: Direct division type • IF counter — HCTR: 0.4 to 25 MHz: for FM IF count — LCTR: 10 to 500 kHz: for AM IF count 1.0 to 20 × 103 Hz: for frequency measurement • Reference frequency — One of 11 frequencies may be selected (when a 10.25 or 10.35 MHz crystal is used) 50, 30*, 25, 12.5, 10, 9*, 6.25, 5, 3.125, 3*, 1 kHz Note: Cannot be used when a 10.25 MHz crystal is used • Phase comparator — Supports dead band control — Built-in unlock detection circuit — Built-in deadlock clearing circuit • Built-in amplifier for forming an active low-pass filter — Built-in operational amplifier for FM high-speed locking — Built-in MOS transistor for AM tuning • Built-in crystal oscillator output buffer • I/O ports — General-purpose I/O: 2 pins — Four input ports (maximum) — Three output ports (maximum) • Serial data I/O — Supports communication with the controller in the CCB format. • Operating ranges — Supply voltage: 4.5 to 5.5 V (VDD) 7.5 to 9.5 V (AVDD) — Operating temperature: –40 to +85°C • Package — SSOP30 Package Dimensions unit: mm 3191A-SSOP30 15 1 16 30 9.75 0.65 (0.43) 0.22 0.15 SANYO: SSOP30 [LC72151V] LC72151V SANYO Electric Co.,Ltd.
