AN18420A

New Contributing to the design of smaller onboard equipment for ETC vehicles. VCO/PLL+IF Single-Chip IC AN18420A for ETC Vehicle  Onboard Equipment „ Overview AN18420A is a single-chip IC that incorporates a VCO/PLL block and an IF block to significantly reduce the size and the number of parts used in the wireless block of onboard 5.8GHz electronic toll collection (ETC) systems. This makes a sizable contribution to the design of more compact onboard equipment for ETC vehicles, a product that is expected to grow in popularity. 6.20±0.10 (6.00) 33 34 23 22 (0.63) 44 R0.30 1(0.63) 12 11 3-C 0.50 (6.00) 6.20±0.10 Unit : mm 0.20±0.10 0.80 max „ Features zSubstantial space-saver for the wireless block of ETC vehicle onboard equipment.
