Transmission Characteristics (Continued)

Unless otherwise noted, limits printed in BOLD characters are guaranteed for V

CC = +5V ±5%,VBB = −5V ±5%;TA = 0˚C to

+70˚C by correlation with 100% electrical testing at T

A = 25˚C. f = 1015.625 Hz, VFXI = 0 dBm0, DR1 = 0 dBm0 PCM code.

Transmit and receive gains programmed for maximum 0 dBm0 test levels (0 dB Gain). All other limits are assured by correla-

tion with other production tests and/or product design and characterization. All signals referenced to GND. Typicals specified

at V

CC = +5V, VBB = −5V, TA = 25˚C.
