MC145146-1

The MC145146-1 is programmed by a 4-bit input, with strobe and adress lines. The MC145146-1 consists of a reference oscillator, 12-bit programmable reference divider, digital phase detector, 10-bit programmable divide-by-N counter, 7-bit divide-by-A counter and the necessary latch circuitry for accepting the 4-bit input data. The typical applications include: (1)CATV; (2)TV tuning; (3)AM/FM radios; (4)scanning receivers; (5)two way radios; (6)amateur radio.

There are some features of MC145146-1 as follows: (1)low power consumption; (2)3.0 to 9.0 V supply range; (3)programmable reference divider for values between 3 and 4095; (4)on- or off-chip reference oscillator operation; (5)dual modulus 4-bit data bus programming; (6)"linearized" digital phase detector enhances transfer function linearity; (7)two error signal options: single ended (three state) and double ended; (8)chip complexity: 5692 FETs or 1423 equivalent gates.

The following is about the maximum ratings of MC145146-1 (voltage reference to VSS): (1)VDD, DC supply voltage: -0.5 to +10 V; (2)VIN, VOUT, input or output voltage (DC or transient): -0.5 to VDD+0.5 V; (3)IIN, IOUT, input or output current (DC or transient), per pin: ±10 mA; (4)IDD, ISS, supply current, VDD or VSS pins: ±30 mA; (5)PD, power dissipation per package: 500 mW; (6)Tstg, storage temperature: -65 to +150; (7)TL, lead temperature (8-second soldering): 260.
