11 / 16 page Transmission Characteristics (Continued) Unless otherwise noted, limits printed in BOLD characters are guaranteed for V CC = +5.0V ±5%, VBB = −5.0V ±5%; TA = −40˚C to +85˚C by correlation with 100% electrical testing at T A = 25˚C. All other limits are assured by correlation with other production tests and/or product design and characterization. GNDA = 0V, f = 1.02 kHz, V IN = 0 dBm0, transmit input amplifier connected for unity gain non inverting. Typicals are specified at V CC = +5.0V, VBB = −5.0V, TA = 25˚C.

Note 4: PPSRX, NPSRX, and CTR–X are measured with a −50 dBm0 activation signal applied to VFXI +. Note 5: TP3054/57 are measured using C message weighted filter for µ-law and psophometric weighted filter for A-law. Note 6: CTX–R @ 1.544 MHz MCLKX freq. is −70 dB max. 50% ±5% BCLKX duty cycle. www.national.com 11 |
