Notes

1. All VDD and VSS connections must be made externally to the same power supply.

2. Electrostatic handling is equivalent to discharging a 100 pF capacitor via a 1.5 kΩ series resistor with a 15 ns rise

time.

3. Electrostatic handling is equivalent to discharging a 200 pF capacitor via a 0 Ω series resistor with a 15 ns rise time.

QUALITY AND RELIABILITY

This device will meet Philips Semiconductors General Quality Specification for Business group “Consumer Integrated

Circuits SNW-FQ-611-Part E”.

SYSTEM PERFORMANCE

Bit Error Rate (BER)

Table 17 shows input signal conditions which typically produce bit error rates of less than 10−3. Signal levels given in dB

are related to the picture carrier reference level (0 dB) and based on the output level of the Philips range of sound IF

down-converter ICs. All measurements at 2nd IF (intercarrier) frequencies (NICAM and FM only) using Philips

Semiconductors TDSD3 Applications Board.

INPUT SIGNAL CONDITIONS

FM overmodulation [NICAM = −20 dB, FM = −10 dB (I)/−13 dB (B/G)]

NICAM level with respect to picture carrier

(FM deviation = ±50 kHz) FM = −10 dB (I)/−13 dB (B/G)

NICAM carrier-to-noise ratio

(NICAM = −20 dB, FM deviation = ±50 kHz) FM = −10 dB (I)/−13 dB (B/G)
