SC11004

The SC11004 is designed as a complete 300/1200 bit per second (bps) modem. All signal processing functions needed for a full duplex, 300/1200 bps, bell 103/212A or V.22 compatible modem, including the FSK and PSK modelators and demodulators and high-band and low-band filters with compromise amplitude and group delay equalizers are integrated on a single chip.

It has seven features. (1)All modulators, demodulators, and filters with compromise equalizers on chip. (2)Call progress mode, tone generators for DTMF, V.22 guard and calling tones. (3)On-chip hybrid. (4)Bell 212A and CCITT V.22 compatible includes notch filter. (5)Serial control interface. (6)Programmable audio port. (7)All loopback diagnostics. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its supply voltage Vcc would be 6V. (2)Its supply voltage Vss would be -6V. (3)Its DC input voltage analog signals would be from Vss-0.6V to Vcc+0.6V. (4)Its DC input voltage digital signals would be from Vss-0.6V to Vcc+0.6V. (5)Its storage temperature range would be from -65°C to 150°C. (6)Its power dissipation would be 500mW. (7)Its lead temperature soldering 10 seconds would be 300°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics are concluded as follow. (1)Its quiescent current would be typ 15mA with test conditions of Vcc=5V and it would be typ 15mA with test conditions of Vss=-5V. (2)Its high level input voltage would be min 2.0V. (3)Its low level input voltage would be max 0.8V. (4)Its maximum output signal would be min 4.0Vpp. (5)Its maximum input signal would be max 4.0Vpp. (6)Its second harmonic distortion would be typ -40dB. (7)Its row output level would be typ 0dBm. (8)Its column output level would be typ 2dBm. (9)Its 550Hz guard tone would be typ -3dB. (10)Its 1800Hz guard tone would be typ -6dB. And so on.
