6 / 23 page TCM37C14A, TCM37C15A PCM COMBO WITH PROGRAMMABLE GAIN CONTROL SLWS018B – JUNE 1996 – REVISED MAY 1998 6 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 electrical characteristics over recommended ranges of supply voltage and operating free-air temperature (outputs not loaded) (unless otherwise noted) (continued) gain and dynamic range, VCC = 5 V, VBB = –5 V, TA = 25°C (see Notes 4, 5, and 6) (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Encoder milliwatt response (transmit gain tolerance) Signal input = 1.064 Vrms for µ-law, Signal input = 1.068 Vrms for A-law ±0.04 ±0.2 dBm0 Encoder milliwatt response variation with temperature and supplies TA = – 40°C – 85°C, supplies = ± 5% ±0.08 dB Digital milliwatt response (receive gain tolerance) relative to zero- transmission level point Signal input per CCITT G.711, output signal = 1 kHz ±0.04 ±0.2 dBm0 Digital milliwatt response variation with temperature and supplies TA = – 40°C – 85°C, supplies = ± 5% ±0.08 dB µ-law RL = 600 Ω 2.76 Zero transmission level point transmit channel (0 dBm0) A-law RL = 600 Ω 2.79 dBm Zero-transmission-level point, transmit channel (0 dBm0) µ-law RL = 900 Ω 1 dBm A-law RL = 900 Ω 1.03 µ-law RL = 600 Ω 5.76 Zero transmission level point receive channel (0 dBm0) A-law RL = 600 Ω 5.79 dBm Zero-transmission-level point, receive channel (0 dBm0) µ-law RL = 900 Ω 4 dBm A-law RL = 900 Ω 4.03 NOTES: 4. Unless otherwise noted, the analog input is a 0-dBm0, 1020-Hz sine wave, where 0 dBm0 is defined as the zero-reference point of the channel under test with unity gain set on the amplifier. This corresponds to an analog signal input of 1.064 Vrms, or an output of 1.503 Vrms. 5. The input amplifier is set for unity gain, noninverting. The digital input is a PCM bit stream generated by passing a 0-dBm0, 1020-Hz sine wave through an ideal encoder. 6. Receive output is measured single ended with the output amplifier in the unity-gain configuration. All output levels are (sin x)/x corrected. gain tracking, reference level = – 10 dBm0 PARAMETER TEST CONDITIONS MIN MAX UNIT 3 > input level ≥ –40 dBm0 ±0.25 Transmit gain tracking error, sinusoidal input – 40 > input level ≥ –50dBm0 ±0.5 dB – 50 > input level ≥ –55 dBm0 ±1.2 3 > input level ≥ –40 dBm0 ±0.25 Receive gain tracking error, sinusoidal input – 40 > input level ≥ –50 dBm0 ±0.5 dB – 50 > input level ≥ –55 dBm0 ±1.2 noise PARAMETER TEST CONDITIONS MIN TYP† MAX UNIT Transmit noise, C-message weighted ANLGIN = AGND 1 7 dBrnC0 Transmit noise, psophometrically weighted ANLGIN = AGND –82 –80 dBm0p Receive noise, C-message-weighted quiet code at PWRO + PCMIN = 11111111 ( µ-law), PCMIN = 11010101 (A-law) 2 5 dBrnC0 Receive noise, psophometrically weighted PCM = lowest positive decode level –81 dBm0p † All typical values are at VBB = –5 V, VCC = 5 V, and TA = 25°C. |
