TC35103F

The TC35103F is a kind of Modem Analog Front-end LSI designed for use in G3 and G2 facsimile machines and data modems using with the TOSHIBA Modem Processor LSI. The device composes a 2-wire half-duples modem and a 4-wire full-duplex modem. It includes receiving and transimission SCF filters, cable equalizers, a group delay equalizer, A-D and D-A converters, a digital controlled programmable gain amplifier, a transmission attenuator, and a transmission mute switch.

There are some features of TC35103F as follows: (1)receiving band-pass filter; (2)transmission low-pass filter; (3)transmission and receiving cable equalizers (4 steps characteristic selectable); (4)1 link fix compromised group delay equalizer; (5)transmission attenuator; (6)digital controlled programmable gain amplifier; (7)A-D and D-A converters; (8)minimum external parts; (9)2 power supply of +5 V or -5 V operation; (10)CMOS low power consumption 75 mW typ; (11)60 pin flat package.

The following is about the maximum ratings of TC35103F: (1)supply voltage, VCC: -0.5 to 7.0 V; (2)supply voltage, VEE: -0.7 to 0.5 V; (3)analog input voltage, VIN: VEE-0.5 to VCC+0.5 V; (4)digital input voltage, VIN: -0.5 to VCC+0.5 V; (5)analog output voltage, VOUT: VEE-0.5 to VCC+0.5 V; (6)digital output voltage, VOUT: -0.5 to VCC+0.5 V; (7)input current, IIN: -20 to +20 mA; (8)operating temperature, Tope: -10 to 70; (9)storage temperature, Tstg: -55 to 150; (10)power dissipation, PD: 600 mW; (11)lead temperature, 10 sec, Tsol: 260.
