Integrated Circuit
High Speed Divider 1/20, 1/100 for VCR
Description:
The NTE1745 is a semiconductor integrated circuit in an 8–Lead SIP type package consisting of a
built–in 1/20 and 1/100 high–speed frequency divider featuring an ECL circuit configuration.
Features:
D High–Speed Operation (fmax = 130MHz)
D Operation at Low Input Amplitudes (180mVp–p Minimum Input Amplitude)
D TTL Level Output
Applications:
FM radio prescalers, digital equipment for consumer and industrial applications
Function:
This divider is based on an ECL circuit configuration. When a frequency up to a maximum of 130MHz
is applied to the TI input pin, 1/20–divided output is produced when the division ratio selection input
pin (M) is low–level or a 1/100–divided output is produced when the division ratio selection input pin
(M) is high–level. The output (TO) is available in the TTL level open collector format.
